We're dividing 921659 by 87 
We want to figure out the number of times 921659 can be divided by 87.

Going ahead to step 1:
87 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 87

Moving on to step 2:
92 divided by 87 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 87 from 92 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 87

Advancing to step 3:
If we divide 51 by 87, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 51 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 87

Moving on to step 4:
If we divide 516 by 87, we get 5 and a remainder of 81.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 435 from 516, we get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 87

Going ahead to step 5:
815 divided by 87 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 1059.0
If we take 783 away from 815, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 87

Going ahead to step 6:
87 can be fit into 329 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 10593.0
If we take 261 away from 329, 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.

On to step 7:
The number 87 fits into 680 7 times, leaving a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 10593.7
If we subtract 609 from 680, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
If we divide 710 by 87, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 10593.78
If we take 696 away from 710, we end up 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.

On to step 9:
When dividing 140 by 87, we get 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 10593.781
Subtracting 87 from 140 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 10:
The number 87 fits into 530 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 10593.7816
Subtract 522 from 530 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 87 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 10593.7816
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
If we divide 800 by 87, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 10593.781609
Subtracting 783 from 800 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
170 divided by 87 is 1 with a remainder of 83.
The next digit of our result is 1. 
Result so far: 10593.7816091
Deduct 87 from 170 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 14:
When dividing 830 by 87, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 10593.78160919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 10593.78160919, with a leftover of 4.7e-08.
