We divide 64539887 by 160
The aim is to understand the frequency of 160 in 64539887.

On to step 1:
160 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 160

Step 2:
When dividing 64 by 160, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 160

Moving on to step 3:
645 divided by 160 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 640 from 645 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 160

Moving on to step 4:
If we divide 53 by 160, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 53, we get 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 160

On to step 5:
If we divide 539 by 160, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 403.0
If we take 480 away from 539, we end up with 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 160

On to step 6:
160 can be fit into 598 3 times, resulting in a remainder of 118.
The number 3 becomes the next digit in our result. 
Result so far: 4033.0
Subtracting 480 from 598 leaves us with 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 160

Step 7:
160 can be fit into 1188 7 times, resulting in a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 40337.0
Subtract 1120 from 1188 to get 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 160

Going ahead to step 8:
When dividing 687 by 160, we get 4 with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 403374.0
Subtracting 640 from 687 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
470 divided by 160 is 2 with a remainder of 150.
Put 2 as the next digit of the answer. 
Result so far: 403374.2
Deduct 320 from 470 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
1500 divided by 160 is 9 with a remainder of 60.
The next digit of our result is 9. 
Result so far: 403374.29
Subtract 1440 from 1500 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
600 divided by 160 is 3 with a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 403374.293
If we subtract 480 from 600, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
160 can be fit into 1200 7 times, resulting in a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 403374.2937
Subtract 1120 from 1200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
160 goes into 800 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 403374.29375
Subtracting 800 from 800 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:
160 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 403374.29375
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.

Let's proceed to step 15:
If we divide 0 by 160, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 403374.29375
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.

The final outcome is 403374.29375, with a leftover of 0.0.
