We're dividing 860029 by 64 
Let's see how many times 64 fits into 860029.

On to step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 64

Going ahead to step 2:
86 divided by 64 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 64 from 86 to get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 64

On to step 3:
64 can be fit into 220 3 times, resulting in a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 192 from 220 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 64

Let's proceed to step 4:
280 divided by 64 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtracting 256 from 280 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 64

On to step 5:
242 divided by 64 is 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 1343.0
Subtracting 192 from 242 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 64

Moving on to step 6:
When dividing 509 by 64, we get 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 13437.0
If we subtract 448 from 509, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
64 can be fit into 610 9 times, resulting in a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 13437.9
If we subtract 576 from 610, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 64, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 13437.95
If we subtract 320 from 340, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
64 goes into 200 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 13437.953
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.

Moving on to step 10:
When dividing 80 by 64, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 13437.9531
Subtract 64 from 80 to 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.

Moving on to step 11:
64 can be fit into 160 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 13437.95312
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.

Going ahead to step 12:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13437.953125
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.

On to step 13:
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: 13437.953125
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.

Let's proceed to step 14:
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: 13437.953125
The remainder is 0 after subtracting 0 from 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 13437.953125, with a leftover of 0.0.
