70651820 ÷ 815 
We want to figure out the number of times 70651820 can be divided by 815.

Advancing to step 1:
When dividing 7 by 815, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 815

Moving on to step 2:
The number 815 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 815

Going ahead to step 3:
706 divided by 815 is 0 with a remainder of 706.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 706 after subtracting 0 from 706.
Take the next digit (5) from the dividend and append it to 706, then repeat: 7065 / 815

Advancing to step 4:
815 can be fit into 7065 8 times, resulting in a remainder of 545.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 545 after subtracting 6520 from 7065.
Fetch the next digit (1) from the dividend, attach it to 545 and continue: 5451 / 815

Advancing to step 5:
The number 815 fits into 5451 6 times, leaving a remainder of 561.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 4890 from 5451 and we're left with 561.
Append the next digit (8) from the dividend to 561 and continue with: 5618 / 815

Advancing to step 6:
5618 divided by 815 is 6 with a remainder of 728.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we take 4890 away from 5618, we end up with 728.
Take the next digit (2) from the dividend and append it to 728, then repeat: 7282 / 815

Advancing to step 7:
815 can be fit into 7282 8 times, resulting in a remainder of 762.
Put 8 as the next digit of the answer. 
Result so far: 8668.0
The remainder is 762 after subtracting 6520 from 7282.
Grab the next digit (0) from the dividend, add it to 762, then carry on: 7620 / 815

Step 8:
7620 divided by 815 is 9 with a remainder of 285.
Put 9 as the next digit of the answer. 
Result so far: 86689.0
Deduct 7335 from 7620 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 9:
When dividing 2850 by 815, we get 3 with a remainder of 405.
Write down 3 as next digit of the result. 
Result so far: 86689.3
Subtract 2445 from 2850 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 10:
The number 815 fits into 4050 4 times, leaving a remainder of 790.
Write down 4 as next digit of the result. 
Result so far: 86689.34
Deduct 3260 from 4050 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Let's proceed to step 11:
815 can be fit into 7900 9 times, resulting in a remainder of 565.
Use 9 as the next digit of our solution. 
Result so far: 86689.349
Subtract 7335 from 7900 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 12:
When dividing 5650 by 815, we get 6 with a remainder of 760.
Record the quotient 6 as the next digit in the result. 
Result so far: 86689.3496
Deduct 4890 from 5650 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.

On to step 13:
When dividing 7600 by 815, we get 9 with a remainder of 265.
Put 9 as the next digit of the answer. 
Result so far: 86689.34969
If we take 7335 away from 7600, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 14:
2650 divided by 815 is 3 with a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 86689.349693
Subtracting 2445 from 2650 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 15:
815 goes into 2050 2 times with a remainder of 420.
The next digit of our result is 2. 
Result so far: 86689.3496932
Subtract 1630 from 2050 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 16:
If we divide 4200 by 815, we get 5 and a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 86689.34969325
The remainder is 125 after subtracting 4075 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 86689.34969325, with a leftover of 1.25e-07.
