We look at the division of 662690 by 87 
We want to divide 662690 by 87.

Going ahead to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 87

Let's proceed to step 2:
87 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 87

Moving on to step 3:
87 goes into 662 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 53 after subtracting 609 from 662.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 87

Moving on to step 4:
536 divided by 87 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 522 from 536 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 87

Moving on to step 5:
87 goes into 149 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 761.0
Subtracting 87 from 149 leaves us with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 87

On to step 6:
620 divided by 87 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 7617.0
Subtract 609 from 620 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.

Going ahead to step 7:
If we divide 110 by 87, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 7617.1
Subtracting 87 from 110 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
When dividing 230 by 87, we get 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 7617.12
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.

Moving on to step 9:
87 can be fit into 560 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 7617.126
If we take 522 away from 560, we end up 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:
87 can be fit into 380 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 7617.1264
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
87 goes into 320 3 times with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 7617.12643
The remainder is 59 after subtracting 261 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 12:
The number 87 fits into 590 6 times, leaving a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 7617.126436
Subtracting 522 from 590 leaves us 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.

Let's proceed to step 13:
87 goes into 680 7 times with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 7617.1264367
The remainder is 71 after subtracting 609 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 14:
The number 87 fits into 710 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 7617.12643678
Deduct 696 from 710 and we're left with 14.
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 7617.12643678, with a leftover of 1.4e-08.
