612921 ÷ 64 
Our goal is to divide 612921 by 64.

Going ahead to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 64

Advancing to step 2:
64 can be fit into 61 0 times, resulting in a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 64

Let's proceed to step 3:
If we divide 612 by 64, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 576 from 612, we get 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 64

Moving on to step 4:
369 divided by 64 is 5 with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtract 320 from 369 to get 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 64

Going ahead to step 5:
If we divide 492 by 64, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 957.0
Subtract 448 from 492 to get 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 64

Advancing to step 6:
64 goes into 441 6 times with a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 9576.0
If we take 384 away from 441, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
When dividing 570 by 64, we get 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 9576.8
Subtracting 512 from 570 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
64 goes into 580 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 9576.89
Subtract 576 from 580 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
64 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9576.89
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
64 can be fit into 400 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 9576.8906
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
160 divided by 64 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 9576.89062
Subtract 128 from 160 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 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9576.890625
If we subtract 320 from 320, 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.

Advancing to step 13:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9576.890625
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.

Moving on to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9576.890625
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 9576.890625, with a leftover of 0.0.
