981405 ÷ 64 
The aim is to understand the frequency of 64 in 981405.

On to step 1:
When dividing 9 by 64, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 64

On to step 2:
98 divided by 64 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 64 from 98 to get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 64

Let's proceed to step 3:
If we divide 341 by 64, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 320 from 341 and we're left with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 64

Advancing to step 4:
64 goes into 214 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
If we subtract 192 from 214, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 64

Advancing to step 5:
The number 64 fits into 220 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 1533.0
If we subtract 192 from 220, we get 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 64

Advancing to step 6:
64 can be fit into 285 4 times, resulting in a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 15334.0
Subtract 256 from 285 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 64 fits into 290 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 15334.4
Subtract 256 from 290 to 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.

Step 8:
When dividing 340 by 64, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 15334.45
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.

Going ahead to step 9:
If we divide 200 by 64, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 15334.453
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.

Moving on to step 10:
When dividing 80 by 64, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 15334.4531
Subtracting 64 from 80 leaves us 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.

Going ahead to step 11:
160 divided by 64 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 15334.45312
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 12:
64 goes into 320 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15334.453125
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.

On to step 13:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15334.453125
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.

On to step 14:
64 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15334.453125
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.

Our division results in 15334.453125 with a remaining 0.0.
