800250 ÷ 64 
The aim is to understand the frequency of 64 in 800250.

Moving on to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 64

On to step 2:
If we divide 80 by 64, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 64 from 80 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 64

Going ahead to step 3:
When dividing 160 by 64, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 32 after subtracting 128 from 160.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 64

Advancing to step 4:
The number 64 fits into 322 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
If we subtract 320 from 322, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 64

Advancing to step 5:
64 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 1250.0
If we subtract 0 from 25, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 64

Step 6:
If we divide 250 by 64, we get 3 and a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 12503.0
Deduct 192 from 250 and we're left 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 7:
The number 64 fits into 580 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 12503.9
Deduct 576 from 580 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 64, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12503.9
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 64, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 12503.906
Subtract 384 from 400 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.

Advancing to step 10:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 12503.9062
If we take 128 away from 160, we end up 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.

Advancing to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12503.90625
If we take 320 away from 320, 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 12:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12503.90625
Subtracting 0 from 0 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.

Moving on to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12503.90625
Deduct 0 from 0 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.

Our division results in 12503.90625 with a remaining 0.0.
