We're dividing 91718351 by 903 
Let's see how many times 903 fits into 91718351.

Advancing to step 1:
The number 903 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 903

Step 2:
The number 903 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 903

Going ahead to step 3:
When dividing 917 by 903, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 903 from 917 and we're left with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 903

Moving on to step 4:
903 can be fit into 141 0 times, resulting in a remainder of 141.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 141 and we're left with 141.
Include the next digit (8) from the dividend after 141, then repeat: 1418 / 903

Moving on to step 5:
When dividing 1418 by 903, we get 1 with a remainder of 515.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtracting 903 from 1418 leaves us with 515.
Grab the next digit (3) from the dividend, add it to 515, then carry on: 5153 / 903

Moving on to step 6:
If we divide 5153 by 903, we get 5 and a remainder of 638.
Write down 5 as next digit of the result. 
Result so far: 1015.0
Subtract 4515 from 5153 to get 638.
Grab the next digit (5) from the dividend, add it to 638, then carry on: 6385 / 903

On to step 7:
6385 divided by 903 is 7 with a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 10157.0
The remainder is 64 after subtracting 6321 from 6385.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 903

Let's proceed to step 8:
903 goes into 641 0 times with a remainder of 641.
The number 0 becomes the next digit in our result. 
Result so far: 101570.0
If we subtract 0 from 641, we get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Moving on to step 9:
When dividing 6410 by 903, we get 7 with a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 101570.7
The remainder is 89 after subtracting 6321 from 6410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 10:
890 divided by 903 is 0 with a remainder of 890.
Use 0 as the next digit of our solution. 
Result so far: 101570.7
Deduct 0 from 890 and we're left with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Going ahead to step 11:
903 goes into 8900 9 times with a remainder of 773.
Write down 9 as next digit of the result. 
Result so far: 101570.709
If we take 8127 away from 8900, we end up with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Advancing to step 12:
903 goes into 7730 8 times with a remainder of 506.
The next digit of our result is 8. 
Result so far: 101570.7098
The remainder is 506 after subtracting 7224 from 7730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 13:
If we divide 5060 by 903, we get 5 and a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 101570.70985
Deduct 4515 from 5060 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 14:
5450 divided by 903 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 101570.709856
Subtracting 5418 from 5450 leaves us with 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 15:
903 can be fit into 320 0 times, resulting in a remainder of 320.
The next digit of our result is 0. 
Result so far: 101570.709856
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 16:
903 goes into 3200 3 times with a remainder of 491.
Write down 3 as next digit of the result. 
Result so far: 101570.70985603
If we subtract 2709 from 3200, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

After the division, we end up with 101570.70985603 and a remainder of 4.91e-07.
