78400962 divided by 631 
We're looking to find how many times 631 goes into 78400962.

Moving on to step 1:
If we divide 7 by 631, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 631

Step 2:
When dividing 78 by 631, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 631

Advancing to step 3:
When dividing 784 by 631, we get 1 with a remainder of 153.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 153 after subtracting 631 from 784.
Grab the next digit (0) from the dividend, add it to 153, then carry on: 1530 / 631

On to step 4:
631 can be fit into 1530 2 times, resulting in a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1262 from 1530, we get 268.
Take the next digit (0) from the dividend and append it to 268, then repeat: 2680 / 631

Let's proceed to step 5:
If we divide 2680 by 631, we get 4 and a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 2524 away from 2680, we end up with 156.
Append the next digit (9) from the dividend to 156 and continue with: 1569 / 631

Advancing to step 6:
The number 631 fits into 1569 2 times, leaving a remainder of 307.
Record the quotient 2 as the next digit in the result. 
Result so far: 1242.0
The remainder is 307 after subtracting 1262 from 1569.
Bring next digit (6) of the dividend behind the 307 and repeat the process: 3076 / 631

Step 7:
631 can be fit into 3076 4 times, resulting in a remainder of 552.
Record the quotient 4 as the next digit in the result. 
Result so far: 12424.0
Deduct 2524 from 3076 and we're left with 552.
Take the next digit (2) from the dividend and append it to 552, then repeat: 5522 / 631

Moving on to step 8:
631 can be fit into 5522 8 times, resulting in a remainder of 474.
Put 8 as the next digit of the answer. 
Result so far: 124248.0
Deduct 5048 from 5522 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 9:
4740 divided by 631 is 7 with a remainder of 323.
The number 7 becomes the next digit in our result. 
Result so far: 124248.7
Deduct 4417 from 4740 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 10:
When dividing 3230 by 631, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 124248.75
Subtracting 3155 from 3230 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
When dividing 750 by 631, we get 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 124248.751
If we subtract 631 from 750, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 12:
1190 divided by 631 is 1 with a remainder of 559.
The number 1 becomes the next digit in our result. 
Result so far: 124248.7511
If we take 631 away from 1190, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

After the division, we end up with 124248.7511 and a remainder of 0.00559.
