We look at the division of 70787470 by 820 
We're looking to find how many times 820 goes into 70787470.

Advancing to step 1:
820 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 820

Advancing to step 2:
When dividing 70 by 820, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 820

Advancing to step 3:
820 can be fit into 707 0 times, resulting in a remainder of 707.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 707 and we're left with 707.
Bring next digit (8) of the dividend behind the 707 and repeat the process: 7078 / 820

Going ahead to step 4:
When dividing 7078 by 820, we get 8 with a remainder of 518.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 518 after subtracting 6560 from 7078.
Bring next digit (7) of the dividend behind the 518 and repeat the process: 5187 / 820

Going ahead to step 5:
820 goes into 5187 6 times with a remainder of 267.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtract 4920 from 5187 to get 267.
Append the next digit (4) from the dividend to 267 and continue with: 2674 / 820

Advancing to step 6:
If we divide 2674 by 820, we get 3 and a remainder of 214.
The next digit of our result is 3. 
Result so far: 863.0
Subtract 2460 from 2674 to get 214.
Fetch the next digit (7) from the dividend, attach it to 214 and continue: 2147 / 820

Going ahead to step 7:
820 can be fit into 2147 2 times, resulting in a remainder of 507.
The number 2 becomes the next digit in our result. 
Result so far: 8632.0
Deduct 1640 from 2147 and we're left with 507.
Append the next digit (0) from the dividend to 507 and continue with: 5070 / 820

Moving on to step 8:
The number 820 fits into 5070 6 times, leaving a remainder of 150.
The next digit of our result is 6. 
Result so far: 86326.0
If we take 4920 away from 5070, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
The number 820 fits into 1500 1 times, leaving a remainder of 680.
Record the quotient 1 as the next digit in the result. 
Result so far: 86326.1
Subtracting 820 from 1500 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 10:
The number 820 fits into 6800 8 times, leaving a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 86326.18
If we take 6560 away from 6800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
The number 820 fits into 2400 2 times, leaving a remainder of 760.
Write down 2 as next digit of the result. 
Result so far: 86326.182
Deduct 1640 from 2400 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 12:
The number 820 fits into 7600 9 times, leaving a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 86326.1829
The remainder is 220 after subtracting 7380 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
The number 820 fits into 2200 2 times, leaving a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 86326.18292
If we subtract 1640 from 2200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 14:
820 can be fit into 5600 6 times, resulting in a remainder of 680.
The next digit of our result is 6. 
Result so far: 86326.182926
If we take 4920 away from 5600, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 15:
820 goes into 6800 8 times with a remainder of 240.
The next digit of our result is 8. 
Result so far: 86326.1829268
If we subtract 6560 from 6800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 16:
If we divide 2400 by 820, we get 2 and a remainder of 760.
Use 2 as the next digit of our solution. 
Result so far: 86326.18292682
Deduct 1640 from 2400 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The quotient of the division is 86326.18292682, and the remainder is 7.6e-07.
