Let's divide 783131 by 87
Let's see how many times 87 fits into 783131.

Advancing to step 1:
87 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 87

Advancing to step 2:
87 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 87

On to step 3:
87 goes into 783 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 0 after subtracting 783 from 783.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 87

Moving on to step 4:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 87

On to step 5:
87 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 900.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 87

Step 6:
131 divided by 87 is 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 9001.0
The remainder is 44 after subtracting 87 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
87 can be fit into 440 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9001.5
Deduct 435 from 440 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 87, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 9001.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 87, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 9001.505
If we take 435 away from 500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
87 goes into 650 7 times with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 9001.5057
Subtract 609 from 650 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
87 goes into 410 4 times with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 9001.50574
Deduct 348 from 410 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
87 can be fit into 620 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 9001.505747
Subtracting 609 from 620 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
The number 87 fits into 110 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 9001.5057471
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
87 can be fit into 230 2 times, resulting in a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 9001.50574712
If we subtract 174 from 230, we 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.

In conclusion, the division gives 9001.50574712 with a balance of 5.6e-08.
