We look at the division of 86336475 by 631 
Let's see how many times 631 fits into 86336475.

Let's proceed to step 1:
The number 631 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 631

Going ahead to step 2:
631 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 631

Step 3:
When dividing 863 by 631, we get 1 with a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 631 from 863 and we're left with 232.
Bring next digit (3) of the dividend behind the 232 and repeat the process: 2323 / 631

Going ahead to step 4:
The number 631 fits into 2323 3 times, leaving a remainder of 430.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1893 from 2323, we get 430.
Take the next digit (6) from the dividend and append it to 430, then repeat: 4306 / 631

Advancing to step 5:
631 goes into 4306 6 times with a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we subtract 3786 from 4306, we get 520.
Take the next digit (4) from the dividend and append it to 520, then repeat: 5204 / 631

On to step 6:
631 goes into 5204 8 times with a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 1368.0
Deduct 5048 from 5204 and we're left with 156.
Fetch the next digit (7) from the dividend, attach it to 156 and continue: 1567 / 631

Step 7:
631 can be fit into 1567 2 times, resulting in a remainder of 305.
Record the quotient 2 as the next digit in the result. 
Result so far: 13682.0
If we subtract 1262 from 1567, we get 305.
Append the next digit (5) from the dividend to 305 and continue with: 3055 / 631

Step 8:
When dividing 3055 by 631, we get 4 with a remainder of 531.
Write down 4 as next digit of the result. 
Result so far: 136824.0
If we take 2524 away from 3055, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 9:
When dividing 5310 by 631, we get 8 with a remainder of 262.
Record the quotient 8 as the next digit in the result. 
Result so far: 136824.8
Subtract 5048 from 5310 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 10:
The number 631 fits into 2620 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 136824.84
Subtracting 2524 from 2620 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 11:
631 goes into 960 1 times with a remainder of 329.
Use 1 as the next digit of our solution. 
Result so far: 136824.841
Deduct 631 from 960 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 12:
3290 divided by 631 is 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 136824.8415
The remainder is 135 after subtracting 3155 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 13:
631 goes into 1350 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 136824.84152
Subtracting 1262 from 1350 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
The number 631 fits into 880 1 times, leaving a remainder of 249.
The number 1 becomes the next digit in our result. 
Result so far: 136824.841521
Subtracting 631 from 880 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 15:
If we divide 2490 by 631, we get 3 and a remainder of 597.
Write down 3 as next digit of the result. 
Result so far: 136824.8415213
If we take 1893 away from 2490, we end up with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 16:
5970 divided by 631 is 9 with a remainder of 291.
Record the quotient 9 as the next digit in the result. 
Result so far: 136824.84152139
Subtracting 5679 from 5970 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

After the division, we end up with 136824.84152139 and a remainder of 2.91e-07.
