We look at the division of 623987 by 64 
We want to divide 623987 by 64.

Moving on to step 1:
64 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 64

Advancing to step 2:
62 divided by 64 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 64

Let's proceed to step 3:
If we divide 623 by 64, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 576 from 623 leaves us with 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 64

Moving on to step 4:
When dividing 479 by 64, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 448 from 479 and we're left with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 64

Moving on to step 5:
318 divided by 64 is 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 974.0
Subtract 256 from 318 to get 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 64

Advancing to step 6:
64 goes into 627 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 9749.0
If we subtract 576 from 627, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
64 goes into 510 7 times with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 9749.7
Deduct 448 from 510 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
If we divide 620 by 64, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 9749.79
The remainder is 44 after subtracting 576 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 64 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 9749.796
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 9749.7968
The remainder is 48 after subtracting 512 from 560.
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 11:
480 divided by 64 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 9749.79687
If we subtract 448 from 480, we 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.

Advancing to step 12:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9749.796875
Deduct 320 from 320 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.

Let's proceed to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 9749.796875
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.

Going ahead to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9749.796875
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.

Our division results in 9749.796875 with a remaining 0.0.
