Let's divide 961631 by 64
Let's see how many times 64 fits into 961631.

On to step 1:
64 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 64

On to step 2:
If we divide 96 by 64, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 64 from 96 to get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 64

Moving on to step 3:
64 goes into 321 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 320 away from 321, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 64

Advancing to step 4:
The number 64 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 150.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 64

On to step 5:
163 divided by 64 is 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 1502.0
Subtracting 128 from 163 leaves us with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 64

Moving on to step 6:
If we divide 351 by 64, we get 5 and a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 15025.0
If we subtract 320 from 351, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 64 fits into 310 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 15025.4
The remainder is 54 after subtracting 256 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
540 divided by 64 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 15025.48
Subtract 512 from 540 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 64, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 15025.484
If we take 256 away from 280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
If we divide 240 by 64, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 15025.4843
If we subtract 192 from 240, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
480 divided by 64 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 15025.48437
If we take 448 away from 480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15025.484375
Subtract 320 from 320 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15025.484375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15025.484375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 15025.484375 and a remainder of 0.0.
