Let's divide 74373881 by 64
The aim is to understand the frequency of 64 in 74373881.

Going ahead to step 1:
When dividing 7 by 64, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 64

Going ahead to step 2:
64 can be fit into 74 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 64 from 74 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 64

Step 3:
The number 64 fits into 103 1 times, leaving a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 39 after subtracting 64 from 103.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 64

On to step 4:
When dividing 397 by 64, we get 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 116.0
If we take 384 away from 397, we end up with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 64

Moving on to step 5:
133 divided by 64 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 1162.0
If we take 128 away from 133, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 64

Going ahead to step 6:
64 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 11620.0
Subtract 0 from 58 to get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 64

Step 7:
The number 64 fits into 588 9 times, leaving a remainder of 12.
The next digit of our result is 9. 
Result so far: 116209.0
If we subtract 576 from 588, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 64

Step 8:
121 divided by 64 is 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 1162091.0
Deduct 64 from 121 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
When dividing 570 by 64, we get 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 1162091.8
Deduct 512 from 570 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.

On to step 10:
580 divided by 64 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1162091.89
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 11:
40 divided by 64 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1162091.89
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.

Advancing to step 12:
64 goes into 400 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1162091.8906
If we subtract 384 from 400, we 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 13:
64 goes into 160 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1162091.89062
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.

Moving on to step 14:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1162091.890625
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.

Moving on to step 15:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1162091.890625
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.

On to step 16:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1162091.890625
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.

After the division, we end up with 1162091.890625 and a remainder of 0.0.
