We divide 64078502 by 631
We want to divide 64078502 by 631.

Going ahead to step 1:
If we divide 6 by 631, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 631

Advancing to step 2:
If we divide 64 by 631, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 631

Let's proceed to step 3:
640 divided by 631 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 631 from 640 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 631

On to step 4:
631 can be fit into 97 0 times, resulting in a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 97 leaves us with 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 631

Going ahead to step 5:
631 goes into 978 1 times with a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 347 after subtracting 631 from 978.
Bring next digit (5) of the dividend behind the 347 and repeat the process: 3475 / 631

Step 6:
If we divide 3475 by 631, we get 5 and a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 1015.0
If we subtract 3155 from 3475, we get 320.
Include the next digit (0) from the dividend after 320, then repeat: 3200 / 631

Moving on to step 7:
When dividing 3200 by 631, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 10155.0
Subtracting 3155 from 3200 leaves us with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 631

Advancing to step 8:
452 divided by 631 is 0 with a remainder of 452.
The number 0 becomes the next digit in our result. 
Result so far: 101550.0
Subtract 0 from 452 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 9:
If we divide 4520 by 631, we get 7 and a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 101550.7
If we subtract 4417 from 4520, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 10:
631 goes into 1030 1 times with a remainder of 399.
Use 1 as the next digit of our solution. 
Result so far: 101550.71
If we take 631 away from 1030, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 11:
631 goes into 3990 6 times with a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 101550.716
The remainder is 204 after subtracting 3786 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 12:
2040 divided by 631 is 3 with a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 101550.7163
If we take 1893 away from 2040, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 13:
1470 divided by 631 is 2 with a remainder of 208.
The next digit of our result is 2. 
Result so far: 101550.71632
Deduct 1262 from 1470 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 14:
631 goes into 2080 3 times with a remainder of 187.
The next digit of our result is 3. 
Result so far: 101550.716323
Subtracting 1893 from 2080 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 15:
631 goes into 1870 2 times with a remainder of 608.
The number 2 becomes the next digit in our result. 
Result so far: 101550.7163232
Deduct 1262 from 1870 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 16:
If we divide 6080 by 631, we get 9 and a remainder of 401.
The next digit of our result is 9. 
Result so far: 101550.71632329
The remainder is 401 after subtracting 5679 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

The final outcome is 101550.71632329, with a leftover of 4.01e-07.
