We look at the division of 87072239 by 821 
Our goal is to divide 87072239 by 821.

Moving on to step 1:
When dividing 8 by 821, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 821

On to step 2:
87 divided by 821 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 821

Moving on to step 3:
The number 821 fits into 870 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 49 after subtracting 821 from 870.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 821

Step 4:
If we divide 497 by 821, we get 0 and a remainder of 497.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 497 leaves us with 497.
Include the next digit (2) from the dividend after 497, then repeat: 4972 / 821

Step 5:
When dividing 4972 by 821, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 46 after subtracting 4926 from 4972.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 821

Let's proceed to step 6:
821 can be fit into 462 0 times, resulting in a remainder of 462.
Put 0 as the next digit of the answer. 
Result so far: 1060.0
If we subtract 0 from 462, we get 462.
Include the next digit (3) from the dividend after 462, then repeat: 4623 / 821

Let's proceed to step 7:
When dividing 4623 by 821, we get 5 with a remainder of 518.
The next digit of our result is 5. 
Result so far: 10605.0
Deduct 4105 from 4623 and we're left with 518.
Bring next digit (9) of the dividend behind the 518 and repeat the process: 5189 / 821

Moving on to step 8:
If we divide 5189 by 821, we get 6 and a remainder of 263.
Use 6 as the next digit of our solution. 
Result so far: 106056.0
Subtracting 4926 from 5189 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
821 can be fit into 2630 3 times, resulting in a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 106056.3
If we take 2463 away from 2630, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 10:
When dividing 1670 by 821, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 106056.32
The remainder is 28 after subtracting 1642 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
821 goes into 280 0 times with a remainder of 280.
The next digit of our result is 0. 
Result so far: 106056.32
The remainder is 280 after subtracting 0 from 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 12:
When dividing 2800 by 821, we get 3 with a remainder of 337.
Record the quotient 3 as the next digit in the result. 
Result so far: 106056.3203
Subtract 2463 from 2800 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 13:
3370 divided by 821 is 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 106056.32034
If we take 3284 away from 3370, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 14:
821 can be fit into 860 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 106056.320341
Subtract 821 from 860 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 15:
821 can be fit into 390 0 times, resulting in a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 106056.320341
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 16:
821 can be fit into 3900 4 times, resulting in a remainder of 616.
Record the quotient 4 as the next digit in the result. 
Result so far: 106056.32034104
If we take 3284 away from 3900, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

The final outcome is 106056.32034104, with a leftover of 6.16e-07.
