We look at the division of 990031 by 64 
We want to figure out the number of times 990031 can be divided by 64.

Advancing to step 1:
64 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 64

Moving on to step 2:
64 can be fit into 99 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 64 from 99, we get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 64

Moving on to step 3:
350 divided by 64 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 320 from 350 leaves us with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 64

Advancing to step 4:
The number 64 fits into 300 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 154.0
Deduct 256 from 300 and we're left with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 64

Step 5:
443 divided by 64 is 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 1546.0
If we subtract 384 from 443, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 64

Going ahead to step 6:
If we divide 591 by 64, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 15469.0
If we subtract 576 from 591, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
64 goes into 150 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 15469.2
If we take 128 away from 150, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
64 goes into 220 3 times with a remainder of 28.
The next digit of our result is 3. 
Result so far: 15469.23
Subtracting 192 from 220 leaves us with 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:
280 divided by 64 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 15469.234
Deduct 256 from 280 and we're left 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.

Going ahead to step 10:
If we divide 240 by 64, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 15469.2343
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 15469.23437
The remainder is 32 after subtracting 448 from 480.
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:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15469.234375
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.

Step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15469.234375
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.

Going ahead to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15469.234375
If we subtract 0 from 0, we 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.

The final outcome is 15469.234375, with a leftover of 0.0.
