879039 divided by 61 
The aim is to understand the frequency of 61 in 879039.

On to step 1:
61 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 61

On to step 2:
87 divided by 61 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 61 from 87 to get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 61

Step 3:
61 can be fit into 269 4 times, resulting in a remainder of 25.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 244 from 269, we get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 61

Step 4:
When dividing 250 by 61, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 244 from 250 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 61

Let's proceed to step 5:
The number 61 fits into 63 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1441.0
Deduct 61 from 63 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 61

Advancing to step 6:
29 divided by 61 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 14410.0
If we take 0 away from 29, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
When dividing 290 by 61, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 14410.4
If we subtract 244 from 290, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
When dividing 460 by 61, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 14410.47
If we subtract 427 from 460, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
The number 61 fits into 330 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 14410.475
Subtract 305 from 330 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 61 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14410.4754
Deduct 244 from 250 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 61 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 14410.4754
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
If we divide 600 by 61, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 14410.475409
If we take 549 away from 600, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
61 can be fit into 510 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 14410.4754098
If we take 488 away from 510, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
220 divided by 61 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 14410.47540983
Deduct 183 from 220 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 14410.47540983, with a leftover of 3.7e-08.
