We're dividing 860111 by 77 
The aim is to understand the frequency of 77 in 860111.

Going ahead to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 77

On to step 2:
77 can be fit into 86 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 86 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 77

Going ahead to step 3:
If we divide 90 by 77, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 77 from 90, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 77

Advancing to step 4:
77 goes into 131 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we take 77 away from 131, we end up with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 77

On to step 5:
When dividing 541 by 77, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1117.0
Subtracting 539 from 541 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 77

Step 6:
The number 77 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 11170.0
Subtracting 0 from 21 leaves us with 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 7:
If we divide 210 by 77, we get 2 and a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 11170.2
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
The number 77 fits into 560 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 11170.27
If we take 539 away from 560, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
210 divided by 77 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 11170.272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
77 goes into 560 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 11170.2727
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
210 divided by 77 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 11170.27272
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
If we divide 560 by 77, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 11170.272727
Subtract 539 from 560 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.

Moving on to step 13:
The number 77 fits into 210 2 times, leaving a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 11170.2727272
The remainder is 56 after subtracting 154 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
77 goes into 560 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 11170.27272727
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 11170.27272727, with a leftover of 2.1e-08.
