Let's divide 81403162 by 64
The aim is to understand the frequency of 64 in 81403162.

On to step 1:
64 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 64

Moving on to step 2:
When dividing 81 by 64, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 64 from 81.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 64

Advancing to step 3:
64 goes into 174 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 46 after subtracting 128 from 174.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 64

Moving on to step 4:
When dividing 460 by 64, we get 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 127.0
Subtract 448 from 460 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 64

Moving on to step 5:
When dividing 123 by 64, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1271.0
If we subtract 64 from 123, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 64

On to step 6:
When dividing 591 by 64, we get 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 12719.0
Subtracting 576 from 591 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 64

Advancing to step 7:
64 can be fit into 156 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 127192.0
Subtracting 128 from 156 leaves us with 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 64

Advancing to step 8:
When dividing 282 by 64, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 1271924.0
If we take 256 away from 282, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
When dividing 260 by 64, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 1271924.4
If we take 256 away from 260, we end up 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.

On to step 10:
When dividing 40 by 64, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1271924.4
Deduct 0 from 40 and we're left 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.

Going ahead to step 11:
400 divided by 64 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1271924.406
If we take 384 away from 400, we end up 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 12:
When dividing 160 by 64, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1271924.4062
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.

Let's proceed to step 13:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1271924.40625
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 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1271924.40625
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 15:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1271924.40625
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 1271924.40625, with a leftover of 0.0.
