Let's divide 84139512 by 903
We want to divide 84139512 by 903.

Let's proceed to step 1:
When dividing 8 by 903, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 903

Going ahead to step 2:
84 divided by 903 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 903

On to step 3:
903 can be fit into 841 0 times, resulting in a remainder of 841.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 841, we get 841.
Take the next digit (3) from the dividend and append it to 841, then repeat: 8413 / 903

Step 4:
If we divide 8413 by 903, we get 9 and a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 8127 from 8413 to get 286.
Take the next digit (9) from the dividend and append it to 286, then repeat: 2869 / 903

Step 5:
903 can be fit into 2869 3 times, resulting in a remainder of 160.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 2709 away from 2869, we end up with 160.
Fetch the next digit (5) from the dividend, attach it to 160 and continue: 1605 / 903

On to step 6:
903 can be fit into 1605 1 times, resulting in a remainder of 702.
The number 1 becomes the next digit in our result. 
Result so far: 931.0
Deduct 903 from 1605 and we're left with 702.
Fetch the next digit (1) from the dividend, attach it to 702 and continue: 7021 / 903

Let's proceed to step 7:
903 can be fit into 7021 7 times, resulting in a remainder of 700.
Use 7 as the next digit of our solution. 
Result so far: 9317.0
If we take 6321 away from 7021, we end up with 700.
Append the next digit (2) from the dividend to 700 and continue with: 7002 / 903

Going ahead to step 8:
If we divide 7002 by 903, we get 7 and a remainder of 681.
Record the quotient 7 as the next digit in the result. 
Result so far: 93177.0
If we subtract 6321 from 7002, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

On to step 9:
903 can be fit into 6810 7 times, resulting in a remainder of 489.
The next digit of our result is 7. 
Result so far: 93177.7
The remainder is 489 after subtracting 6321 from 6810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 10:
When dividing 4890 by 903, we get 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 93177.75
If we take 4515 away from 4890, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 11:
3750 divided by 903 is 4 with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 93177.754
Subtracting 3612 from 3750 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 12:
If we divide 1380 by 903, we get 1 and a remainder of 477.
Put 1 as the next digit of the answer. 
Result so far: 93177.7541
Subtracting 903 from 1380 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 13:
The number 903 fits into 4770 5 times, leaving a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 93177.75415
If we subtract 4515 from 4770, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 14:
2550 divided by 903 is 2 with a remainder of 744.
Use 2 as the next digit of our solution. 
Result so far: 93177.754152
Subtract 1806 from 2550 to get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 15:
When dividing 7440 by 903, we get 8 with a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 93177.7541528
If we subtract 7224 from 7440, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 16:
903 goes into 2160 2 times with a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 93177.75415282
Subtract 1806 from 2160 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 93177.75415282 with a remaining 3.54e-07.
