We look at the division of 810847 by 61 
The aim is to understand the frequency of 61 in 810847.

Moving on to step 1:
61 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 61

Advancing to step 2:
61 goes into 81 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 61 from 81 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 61

Going ahead to step 3:
The number 61 fits into 200 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 17 after subtracting 183 from 200.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 61

Let's proceed to step 4:
When dividing 178 by 61, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
If we take 122 away from 178, we end up with 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 61

Step 5:
61 goes into 564 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 1329.0
The remainder is 15 after subtracting 549 from 564.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 61

Let's proceed to step 6:
When dividing 157 by 61, we get 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 13292.0
Deduct 122 from 157 and we're left 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.

Going ahead to step 7:
When dividing 350 by 61, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 13292.5
Subtract 305 from 350 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
When dividing 450 by 61, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 13292.57
If we subtract 427 from 450, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
230 divided by 61 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 13292.573
The remainder is 47 after subtracting 183 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
61 goes into 470 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 13292.5737
If we subtract 427 from 470, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
61 can be fit into 430 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 13292.57377
The remainder is 3 after subtracting 427 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 13292.57377 with a remaining 3e-06.
