64504391 ÷ 631 
Let's see how many times 631 fits into 64504391.

Moving on to step 1:
631 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 631

Let's proceed to step 2:
64 divided by 631 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 631

Advancing to step 3:
645 divided by 631 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 631 from 645 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 631

Let's proceed to step 4:
When dividing 140 by 631, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 140 to get 140.
Append the next digit (4) from the dividend to 140 and continue with: 1404 / 631

Moving on to step 5:
631 goes into 1404 2 times with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 1262 away from 1404, we end up with 142.
Grab the next digit (3) from the dividend, add it to 142, then carry on: 1423 / 631

Going ahead to step 6:
When dividing 1423 by 631, we get 2 with a remainder of 161.
Record the quotient 2 as the next digit in the result. 
Result so far: 1022.0
Subtracting 1262 from 1423 leaves us with 161.
Take the next digit (9) from the dividend and append it to 161, then repeat: 1619 / 631

Going ahead to step 7:
If we divide 1619 by 631, we get 2 and a remainder of 357.
Use 2 as the next digit of our solution. 
Result so far: 10222.0
Subtracting 1262 from 1619 leaves us with 357.
Fetch the next digit (1) from the dividend, attach it to 357 and continue: 3571 / 631

Let's proceed to step 8:
The number 631 fits into 3571 5 times, leaving a remainder of 416.
Put 5 as the next digit of the answer. 
Result so far: 102225.0
If we subtract 3155 from 3571, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
When dividing 4160 by 631, we get 6 with a remainder of 374.
Record the quotient 6 as the next digit in the result. 
Result so far: 102225.6
If we take 3786 away from 4160, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 10:
3740 divided by 631 is 5 with a remainder of 585.
Write down 5 as next digit of the result. 
Result so far: 102225.65
Subtracting 3155 from 3740 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Moving on to step 11:
5850 divided by 631 is 9 with a remainder of 171.
The next digit of our result is 9. 
Result so far: 102225.659
The remainder is 171 after subtracting 5679 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 12:
631 can be fit into 1710 2 times, resulting in a remainder of 448.
The next digit of our result is 2. 
Result so far: 102225.6592
Subtract 1262 from 1710 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 13:
The number 631 fits into 4480 7 times, leaving a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 102225.65927
If we take 4417 away from 4480, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 14:
The number 631 fits into 630 0 times, leaving a remainder of 630.
The next digit of our result is 0. 
Result so far: 102225.65927
If we take 0 away from 630, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 15:
The number 631 fits into 6300 9 times, leaving a remainder of 621.
Put 9 as the next digit of the answer. 
Result so far: 102225.6592709
Deduct 5679 from 6300 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Let's proceed to step 16:
If we divide 6210 by 631, we get 9 and a remainder of 531.
Use 9 as the next digit of our solution. 
Result so far: 102225.65927099
If we subtract 5679 from 6210, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Our division results in 102225.65927099 with a remaining 5.31e-07.
