Let's divide 791845 by 61
The aim is to understand the frequency of 61 in 791845.

Going ahead to step 1:
When dividing 7 by 61, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 61

On to step 2:
The number 61 fits into 79 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 61 from 79, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 61

On to step 3:
The number 61 fits into 181 2 times, leaving a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 122 from 181 to get 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 61

Moving on to step 4:
The number 61 fits into 598 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtract 549 from 598 to get 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 61

Step 5:
If we divide 494 by 61, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1298.0
If we subtract 488 from 494, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 61

On to step 6:
61 goes into 65 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 12981.0
If we subtract 61 from 65, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 61 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12981.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 61, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 12981.06
Subtract 366 from 400 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 9:
When dividing 340 by 61, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 12981.065
If we take 305 away from 340, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
If we divide 350 by 61, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 12981.0655
The remainder is 45 after subtracting 305 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 12981.0655, with a leftover of 0.00045.
