615213 divided by 64 
Let's see how many times 64 fits into 615213.

Let's proceed to step 1:
The number 64 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 64

Moving on to step 2:
The number 64 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 64

Advancing to step 3:
The number 64 fits into 615 9 times, leaving a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 576 from 615 and we're left with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 64

Moving on to step 4:
When dividing 392 by 64, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we subtract 384 from 392, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 64

Let's proceed to step 5:
81 divided by 64 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 961.0
The remainder is 17 after subtracting 64 from 81.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 64

Step 6:
173 divided by 64 is 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 9612.0
Deduct 128 from 173 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
The number 64 fits into 450 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 9612.7
If we subtract 448 from 450, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 64, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9612.7
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
64 goes into 200 3 times with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 9612.703
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 9612.7031
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 9612.70312
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9612.703125
Subtracting 320 from 320 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.

On to step 13:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9612.703125
Subtract 0 from 0 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.

On to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9612.703125
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 final result is 9612.703125 with a remainder of 0.0.
