Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 908

Step 2:
99 divided by 908 is 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 908

On to step 3:
If we divide 996 by 908, we get 1 and a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 908 from 996 to get 88.
Fetch the next digit (4) from the dividend, attach it to 88 and continue: 884 / 908

908 can be fit into 884 0 times, resulting in a remainder of 884.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 884, we get 884.
Append the next digit (0) from the dividend to 884 and continue with: 8840 / 908

On to step 5:
8840 divided by 908 is 9 with a remainder of 668.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 8172 from 8840, we get 668.
Grab the next digit (7) from the dividend, add it to 668, then carry on: 6687 / 908

Advancing to step 6:
When dividing 6687 by 908, we get 7 with a remainder of 331.
The number 7 becomes the next digit in our result. 
Result so far: 1097.0
Subtract 6356 from 6687 to get 331.
Include the next digit (6) from the dividend after 331, then repeat: 3316 / 908

On to step 7:
The number 908 fits into 3316 3 times, leaving a remainder of 592.
The next digit of our result is 3. 
Result so far: 10973.0
If we subtract 2724 from 3316, we get 592.
Fetch the next digit (1) from the dividend, attach it to 592 and continue: 5921 / 908

Moving on to step 8:
The number 908 fits into 5921 6 times, leaving a remainder of 473.
The number 6 becomes the next digit in our result. 
Result so far: 109736.0
The remainder is 473 after subtracting 5448 from 5921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 9:
908 goes into 4730 5 times with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 109736.5
Deduct 4540 from 4730 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
908 goes into 1900 2 times with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 109736.52
Subtracting 1816 from 1900 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
When dividing 840 by 908, we get 0 with a remainder of 840.
The number 0 becomes the next digit in our result. 
Result so far: 109736.52
Subtracting 0 from 840 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 12:
8400 divided by 908 is 9 with a remainder of 228.
The next digit of our result is 9. 
Result so far: 109736.5209
If we subtract 8172 from 8400, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 13:
If we divide 2280 by 908, we get 2 and a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 109736.52092
Subtract 1816 from 2280 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 14:
4640 divided by 908 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 109736.520925
Subtracting 4540 from 4640 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
If we divide 1000 by 908, we get 1 and a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 109736.5209251
Subtract 908 from 1000 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 16:
If we divide 920 by 908, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 109736.52092511
The remainder is 12 after subtracting 908 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 109736.52092511, and the remainder is 1.2e-08.
