903651 ÷ 64 
The aim is to understand the frequency of 64 in 903651.

Going ahead to step 1:
64 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 64

Advancing to step 2:
If we divide 90 by 64, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 64 from 90 leaves us with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 64

On to step 3:
If we divide 263 by 64, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 7 after subtracting 256 from 263.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 64

On to step 4:
64 goes into 76 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 64 from 76 leaves us with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 64

On to step 5:
64 can be fit into 125 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1411.0
The remainder is 61 after subtracting 64 from 125.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 64

Step 6:
If we divide 611 by 64, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 14119.0
If we subtract 576 from 611, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
If we divide 350 by 64, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 14119.5
If we take 320 away from 350, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 64, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 14119.54
Subtract 256 from 300 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
64 can be fit into 440 6 times, resulting in a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 14119.546
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 14119.5468
Subtracting 512 from 560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
480 divided by 64 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 14119.54687
If we subtract 448 from 480, we 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.

On to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 14119.546875
Deduct 320 from 320 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.

Advancing to step 13:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14119.546875
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.

On to step 14:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14119.546875
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 quotient of the division is 14119.546875, and the remainder is 0.0.
