We're dividing 16797397 by 61 
The aim is to understand the frequency of 61 in 16797397.

On to step 1:
If we divide 1 by 61, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 61

Step 2:
61 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 61

Step 3:
If we divide 167 by 61, we get 2 and a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 45 after subtracting 122 from 167.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 61

On to step 4:
61 can be fit into 459 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 32 after subtracting 427 from 459.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 61

On to step 5:
If we divide 327 by 61, we get 5 and a remainder of 22.
The next digit of our result is 5. 
Result so far: 275.0
Deduct 305 from 327 and we're left with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 61

On to step 6:
When dividing 223 by 61, we get 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 2753.0
Deduct 183 from 223 and we're left with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 61

On to step 7:
409 divided by 61 is 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 27536.0
Subtract 366 from 409 to get 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 61

Advancing to step 8:
If we divide 437 by 61, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 275367.0
Subtracting 427 from 437 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 61 fits into 100 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 275367.1
Subtracting 61 from 100 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
When dividing 390 by 61, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 275367.16
If we subtract 366 from 390, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
61 can be fit into 240 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 275367.163
The remainder is 57 after subtracting 183 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
570 divided by 61 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 275367.1639
Subtract 549 from 570 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
The number 61 fits into 210 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 275367.16393
Subtract 183 from 210 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
When dividing 270 by 61, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 275367.163934
Deduct 244 from 270 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 15:
61 can be fit into 260 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 275367.1639344
The remainder is 16 after subtracting 244 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 275367.1639344 and a remainder of 1.6e-07.
