99267378 divided by 631 
We want to figure out the number of times 99267378 can be divided by 631.

Going ahead to step 1:
631 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 631

Advancing to step 2:
The number 631 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 631

Let's proceed to step 3:
When dividing 992 by 631, we get 1 with a remainder of 361.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 631 from 992 leaves us with 361.
Take the next digit (6) from the dividend and append it to 361, then repeat: 3616 / 631

On to step 4:
When dividing 3616 by 631, we get 5 with a remainder of 461.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 3155 from 3616 and we're left with 461.
Take the next digit (7) from the dividend and append it to 461, then repeat: 4617 / 631

Let's proceed to step 5:
4617 divided by 631 is 7 with a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Subtracting 4417 from 4617 leaves us with 200.
Grab the next digit (3) from the dividend, add it to 200, then carry on: 2003 / 631

On to step 6:
If we divide 2003 by 631, we get 3 and a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 1573.0
Subtracting 1893 from 2003 leaves us with 110.
Grab the next digit (7) from the dividend, add it to 110, then carry on: 1107 / 631

Going ahead to step 7:
If we divide 1107 by 631, we get 1 and a remainder of 476.
Write down 1 as next digit of the result. 
Result so far: 15731.0
If we take 631 away from 1107, we end up with 476.
Append the next digit (8) from the dividend to 476 and continue with: 4768 / 631

Going ahead to step 8:
4768 divided by 631 is 7 with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 157317.0
Subtracting 4417 from 4768 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 9:
When dividing 3510 by 631, we get 5 with a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 157317.5
If we subtract 3155 from 3510, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 10:
If we divide 3550 by 631, we get 5 and a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 157317.55
If we subtract 3155 from 3550, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

After the division, we end up with 157317.55 and a remainder of 0.395.
