812354 ÷ 64 
We want to figure out the number of times 812354 can be divided by 64.

Step 1:
64 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 64

Step 2:
When dividing 81 by 64, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 64 from 81 leaves us with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 64

On to step 3:
64 goes into 172 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 44 after subtracting 128 from 172.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 64

On to step 4:
64 can be fit into 443 6 times, resulting in a remainder of 59.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 384 from 443 to get 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 64

Step 5:
When dividing 595 by 64, we get 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1269.0
Deduct 576 from 595 and we're left with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 64

Advancing to step 6:
When dividing 194 by 64, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 12693.0
If we subtract 192 from 194, 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.

On to step 7:
64 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12693.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
64 goes into 200 3 times with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 12693.03
If we take 192 away from 200, we end up 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 9:
64 goes into 80 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 12693.031
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 10:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12693.0312
Subtracting 128 from 160 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 12693.03125
The remainder is 0 after subtracting 320 from 320.
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 12:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12693.03125
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 13:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12693.03125
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.

Our division results in 12693.03125 with a remaining 0.0.
