We're dividing 852769 by 61 
The aim is to understand the frequency of 61 in 852769.

Let's proceed to step 1:
When dividing 8 by 61, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 61

Going ahead to step 2:
61 goes into 85 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 24 after subtracting 61 from 85.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 61

Let's proceed to step 3:
If we divide 242 by 61, we get 3 and a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 183 from 242 to get 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 61

Let's proceed to step 4:
61 goes into 597 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 549 from 597, we get 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 61

On to step 5:
When dividing 486 by 61, we get 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 1397.0
Subtract 427 from 486 to get 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 61

On to step 6:
The number 61 fits into 599 9 times, leaving a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 13979.0
Subtract 549 from 599 to 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.

Step 7:
If we divide 500 by 61, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 13979.8
Deduct 488 from 500 and we're left 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.

Moving on to step 8:
61 goes into 120 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 13979.81
Subtract 61 from 120 to 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.

Step 9:
590 divided by 61 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 13979.819
The remainder is 41 after subtracting 549 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
61 can be fit into 410 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 13979.8196
Deduct 366 from 410 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
440 divided by 61 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 13979.81967
If we subtract 427 from 440, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
130 divided by 61 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 13979.819672
If we subtract 122 from 130, we 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.

Advancing to step 13:
When dividing 80 by 61, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 13979.8196721
If we subtract 61 from 80, we 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 14:
61 can be fit into 190 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13979.81967213
If we take 183 away from 190, we end up 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 13979.81967213, with a leftover of 7e-09.
