51590704 divided by 87 
Our goal is to divide 51590704 by 87.

Step 1:
When dividing 5 by 87, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 87

Step 2:
The number 87 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 87

Step 3:
The number 87 fits into 515 5 times, leaving a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 435 away from 515, we end up with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 87

On to step 4:
The number 87 fits into 809 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 59.0
If we take 783 away from 809, we end up with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 87

Going ahead to step 5:
260 divided by 87 is 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 592.0
Subtracting 174 from 260 leaves us with 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 87

Advancing to step 6:
87 can be fit into 867 9 times, resulting in a remainder of 84.
The next digit of our result is 9. 
Result so far: 5929.0
If we take 783 away from 867, we end up with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 87

Advancing to step 7:
When dividing 840 by 87, we get 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 59299.0
Subtracting 783 from 840 leaves us with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 87

Step 8:
The number 87 fits into 574 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 592996.0
Deduct 522 from 574 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
When dividing 520 by 87, we get 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 592996.5
Subtract 435 from 520 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
850 divided by 87 is 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 592996.59
Deduct 783 from 850 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
If we divide 670 by 87, we get 7 and a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 592996.597
If we take 609 away from 670, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 12:
87 goes into 610 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 592996.5977
If we subtract 609 from 610, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 592996.5977, with a leftover of 1e-05.
