Let's divide 903868 by 91
Our goal is to divide 903868 by 91.

Step 1:
If we divide 9 by 91, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 91

Advancing to step 2:
If we divide 90 by 91, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 91

Going ahead to step 3:
If we divide 903 by 91, we get 9 and a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 819 from 903 to get 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 91

On to step 4:
When dividing 848 by 91, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtracting 819 from 848 leaves us with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 91

Let's proceed to step 5:
If we divide 296 by 91, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 993.0
Deduct 273 from 296 and we're left with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 91

Let's proceed to step 6:
238 divided by 91 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 9932.0
The remainder is 56 after subtracting 182 from 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
When dividing 560 by 91, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 9932.6
If we take 546 away from 560, 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.

Step 8:
140 divided by 91 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 9932.61
Subtract 91 from 140 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
The number 91 fits into 490 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 9932.615
If we subtract 455 from 490, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
The number 91 fits into 350 3 times, leaving a remainder of 77.
The next digit of our result is 3. 
Result so far: 9932.6153
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 11:
If we divide 770 by 91, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 9932.61538
Deduct 728 from 770 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
91 goes into 420 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9932.615384
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
If we divide 560 by 91, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 9932.6153846
If we take 546 away from 560, 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 14:
91 goes into 140 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 9932.61538461
The remainder is 49 after subtracting 91 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 9932.61538461 and a remainder of 4.9e-08.
