Let's divide 91008974 by 631
We want to divide 91008974 by 631.

Going ahead to step 1:
When dividing 9 by 631, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 631

On to step 2:
631 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 631

Let's proceed to step 3:
631 can be fit into 910 1 times, resulting in a remainder of 279.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 631 away from 910, we end up with 279.
Bring next digit (0) of the dividend behind the 279 and repeat the process: 2790 / 631

Going ahead to step 4:
2790 divided by 631 is 4 with a remainder of 266.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 266 after subtracting 2524 from 2790.
Append the next digit (8) from the dividend to 266 and continue with: 2668 / 631

Let's proceed to step 5:
2668 divided by 631 is 4 with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Subtracting 2524 from 2668 leaves us with 144.
Append the next digit (9) from the dividend to 144 and continue with: 1449 / 631

Moving on to step 6:
If we divide 1449 by 631, we get 2 and a remainder of 187.
Use 2 as the next digit of our solution. 
Result so far: 1442.0
If we take 1262 away from 1449, we end up with 187.
Take the next digit (7) from the dividend and append it to 187, then repeat: 1877 / 631

Moving on to step 7:
The number 631 fits into 1877 2 times, leaving a remainder of 615.
The number 2 becomes the next digit in our result. 
Result so far: 14422.0
If we subtract 1262 from 1877, we get 615.
Append the next digit (4) from the dividend to 615 and continue with: 6154 / 631

On to step 8:
631 goes into 6154 9 times with a remainder of 475.
Write down 9 as next digit of the result. 
Result so far: 144229.0
If we take 5679 away from 6154, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 9:
4750 divided by 631 is 7 with a remainder of 333.
Write down 7 as next digit of the result. 
Result so far: 144229.7
Deduct 4417 from 4750 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 10:
631 can be fit into 3330 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 144229.75
Deduct 3155 from 3330 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 11:
The number 631 fits into 1750 2 times, leaving a remainder of 488.
The next digit of our result is 2. 
Result so far: 144229.752
Deduct 1262 from 1750 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 12:
631 goes into 4880 7 times with a remainder of 463.
Record the quotient 7 as the next digit in the result. 
Result so far: 144229.7527
Subtracting 4417 from 4880 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Step 13:
If we divide 4630 by 631, we get 7 and a remainder of 213.
The next digit of our result is 7. 
Result so far: 144229.75277
Subtracting 4417 from 4630 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The final result is 144229.75277 with a remainder of 0.000213.
