We divide 16215 by 61
The aim is to understand the frequency of 61 in 16215.

Advancing to step 1:
The number 61 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 61

On to step 2:
When dividing 16 by 61, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 61

Let's proceed to step 3:
If we divide 162 by 61, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 40 after subtracting 122 from 162.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 61

Let's proceed to step 4:
61 goes into 401 6 times with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 35 after subtracting 366 from 401.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 61

On to step 5:
61 goes into 355 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
If we subtract 305 from 355, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 6:
The number 61 fits into 500 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 265.8
If we take 488 away from 500, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 61 is 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 265.81
If we subtract 61 from 120, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 8:
590 divided by 61 is 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 265.819
If we take 549 away from 590, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
If we divide 410 by 61, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 265.8196
Subtract 366 from 410 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 10:
61 goes into 440 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 265.81967
If we take 427 away from 440, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
61 goes into 130 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 265.819672
Subtract 122 from 130 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
If we divide 80 by 61, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 265.8196721
Subtract 61 from 80 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
If we divide 190 by 61, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 265.81967213
Subtracting 183 from 190 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 265.81967213, with a leftover of 7e-09.
