63618643 ÷ 631 
Let's see how many times 631 fits into 63618643.

Advancing to step 1:
If we divide 6 by 631, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 631

Step 2:
When dividing 63 by 631, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 631

Let's proceed to step 3:
631 goes into 636 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 631 from 636 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 631

Moving on to step 4:
If we divide 51 by 631, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 51, we get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 631

Step 5:
The number 631 fits into 518 0 times, leaving a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 518 leaves us with 518.
Grab the next digit (6) from the dividend, add it to 518, then carry on: 5186 / 631

Going ahead to step 6:
631 can be fit into 5186 8 times, resulting in a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 1008.0
Deduct 5048 from 5186 and we're left with 138.
Bring next digit (4) of the dividend behind the 138 and repeat the process: 1384 / 631

Going ahead to step 7:
If we divide 1384 by 631, we get 2 and a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 10082.0
If we subtract 1262 from 1384, we get 122.
Append the next digit (3) from the dividend to 122 and continue with: 1223 / 631

Let's proceed to step 8:
If we divide 1223 by 631, we get 1 and a remainder of 592.
Write down 1 as next digit of the result. 
Result so far: 100821.0
Subtracting 631 from 1223 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 9:
The number 631 fits into 5920 9 times, leaving a remainder of 241.
Write down 9 as next digit of the result. 
Result so far: 100821.9
Deduct 5679 from 5920 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 10:
When dividing 2410 by 631, we get 3 with a remainder of 517.
Put 3 as the next digit of the answer. 
Result so far: 100821.93
Subtract 1893 from 2410 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 11:
631 can be fit into 5170 8 times, resulting in a remainder of 122.
The next digit of our result is 8. 
Result so far: 100821.938
Subtracting 5048 from 5170 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 12:
The number 631 fits into 1220 1 times, leaving a remainder of 589.
Put 1 as the next digit of the answer. 
Result so far: 100821.9381
If we take 631 away from 1220, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Going ahead to step 13:
5890 divided by 631 is 9 with a remainder of 211.
Put 9 as the next digit of the answer. 
Result so far: 100821.93819
Subtract 5679 from 5890 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 14:
631 goes into 2110 3 times with a remainder of 217.
The next digit of our result is 3. 
Result so far: 100821.938193
The remainder is 217 after subtracting 1893 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 15:
When dividing 2170 by 631, we get 3 with a remainder of 277.
Use 3 as the next digit of our solution. 
Result so far: 100821.9381933
Subtracting 1893 from 2170 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

After the division, we end up with 100821.9381933 and a remainder of 2.77e-06.
