Let's divide 817724 by 87
Our goal is to divide 817724 by 87.

Going ahead to step 1:
87 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 87

Advancing to step 2:
If we divide 81 by 87, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 87

Let's proceed to step 3:
If we divide 817 by 87, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 34 after subtracting 783 from 817.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 87

Let's proceed to step 4:
If we divide 347 by 87, we get 3 and a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 261 from 347 to get 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 87

On to step 5:
The number 87 fits into 862 9 times, leaving a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 939.0
Deduct 783 from 862 and we're left with 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 87

Let's proceed to step 6:
If we divide 794 by 87, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 9399.0
Subtract 783 from 794 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 87, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 9399.1
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
When dividing 230 by 87, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 9399.12
Subtract 174 from 230 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
87 goes into 560 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 9399.126
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
380 divided by 87 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 9399.1264
Deduct 348 from 380 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
87 can be fit into 320 3 times, resulting in a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 9399.12643
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
87 can be fit into 590 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 9399.126436
If we take 522 away from 590, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 13:
If we divide 680 by 87, we get 7 and a remainder of 71.
The next digit of our result is 7. 
Result so far: 9399.1264367
Deduct 609 from 680 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
87 can be fit into 710 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 9399.12643678
The remainder is 14 after subtracting 696 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 9399.12643678, with a leftover of 1.4e-08.
