We're dividing 70236660 by 820 
Our goal is to divide 70236660 by 820.

Let's proceed to step 1:
The number 820 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 820

Step 2:
820 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 820

Going ahead to step 3:
702 divided by 820 is 0 with a remainder of 702.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 702 after subtracting 0 from 702.
Bring next digit (3) of the dividend behind the 702 and repeat the process: 7023 / 820

On to step 4:
The number 820 fits into 7023 8 times, leaving a remainder of 463.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6560 from 7023 and we're left with 463.
Bring next digit (6) of the dividend behind the 463 and repeat the process: 4636 / 820

Step 5:
When dividing 4636 by 820, we get 5 with a remainder of 536.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 4100 from 4636 to get 536.
Grab the next digit (6) from the dividend, add it to 536, then carry on: 5366 / 820

Step 6:
The number 820 fits into 5366 6 times, leaving a remainder of 446.
Record the quotient 6 as the next digit in the result. 
Result so far: 856.0
If we subtract 4920 from 5366, we get 446.
Grab the next digit (6) from the dividend, add it to 446, then carry on: 4466 / 820

Advancing to step 7:
820 goes into 4466 5 times with a remainder of 366.
Use 5 as the next digit of our solution. 
Result so far: 8565.0
The remainder is 366 after subtracting 4100 from 4466.
Include the next digit (0) from the dividend after 366, then repeat: 3660 / 820

Moving on to step 8:
When dividing 3660 by 820, we get 4 with a remainder of 380.
The number 4 becomes the next digit in our result. 
Result so far: 85654.0
Subtracting 3280 from 3660 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
The number 820 fits into 3800 4 times, leaving a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 85654.4
Subtracting 3280 from 3800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
820 goes into 5200 6 times with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 85654.46
If we take 4920 away from 5200, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
The number 820 fits into 2800 3 times, leaving a remainder of 340.
Write down 3 as next digit of the result. 
Result so far: 85654.463
If we take 2460 away from 2800, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
The number 820 fits into 3400 4 times, leaving a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 85654.4634
Deduct 3280 from 3400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
820 goes into 1200 1 times with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 85654.46341
Subtracting 820 from 1200 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
820 goes into 3800 4 times with a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 85654.463414
Subtracting 3280 from 3800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 15:
5200 divided by 820 is 6 with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 85654.4634146
If we take 4920 away from 5200, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
The number 820 fits into 2800 3 times, leaving a remainder of 340.
Write down 3 as next digit of the result. 
Result so far: 85654.46341463
Subtract 2460 from 2800 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 85654.46341463 with a remainder of 3.4e-07.
