We look at the division of 99444559 by 64 
We want to divide 99444559 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.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 64

Step 2:
When dividing 99 by 64, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 35 after subtracting 64 from 99.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 64

Going ahead to step 3:
When dividing 354 by 64, we get 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 320 away from 354, we end up with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 64

Advancing to step 4:
When dividing 344 by 64, we get 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we subtract 320 from 344, we get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 64

On to step 5:
When dividing 244 by 64, we get 3 with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 1553.0
Deduct 192 from 244 and we're left with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 64

Advancing to step 6:
The number 64 fits into 525 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 15538.0
Deduct 512 from 525 and we're left with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 64

On to step 7:
The number 64 fits into 135 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 155382.0
Deduct 128 from 135 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 64

On to step 8:
If we divide 79 by 64, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1553821.0
Subtracting 64 from 79 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
If we divide 150 by 64, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1553821.2
The remainder is 22 after subtracting 128 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
When dividing 220 by 64, we get 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 1553821.23
If we subtract 192 from 220, we 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.

Step 11:
If we divide 280 by 64, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 1553821.234
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.

Moving on to step 12:
When dividing 240 by 64, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 1553821.2343
Deduct 192 from 240 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
If we divide 480 by 64, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 1553821.23437
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
If we divide 320 by 64, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1553821.234375
If we take 320 away from 320, we end up 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.

Let's proceed to step 15:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1553821.234375
If we take 0 away from 0, we end up 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.

On to step 16:
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: 1553821.234375
If we take 0 away from 0, we end up 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.

The quotient of the division is 1553821.234375, and the remainder is 0.0.
