We're dividing 68707942 by 180 
The aim is to understand the frequency of 180 in 68707942.

On to step 1:
When dividing 6 by 180, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 180

Going ahead to step 2:
If we divide 68 by 180, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 180

Going ahead to step 3:
The number 180 fits into 687 3 times, leaving a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 540 away from 687, we end up with 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 180

Moving on to step 4:
The number 180 fits into 1470 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 30 after subtracting 1440 from 1470.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 180

Step 5:
180 can be fit into 307 1 times, resulting in a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Subtract 180 from 307 to get 127.
Include the next digit (9) from the dividend after 127, then repeat: 1279 / 180

Step 6:
180 can be fit into 1279 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 3817.0
Subtract 1260 from 1279 to get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 180

On to step 7:
194 divided by 180 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 38171.0
Subtract 180 from 194 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 180

Step 8:
180 goes into 142 0 times with a remainder of 142.
Record the quotient 0 as the next digit in the result. 
Result so far: 381710.0
The remainder is 142 after subtracting 0 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 9:
1420 divided by 180 is 7 with a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 381710.7
Deduct 1260 from 1420 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
180 can be fit into 1600 8 times, resulting in a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 381710.78
If we subtract 1440 from 1600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
180 can be fit into 1600 8 times, resulting in a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 381710.788
Subtract 1440 from 1600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 381710.788, and the remainder is 0.016.
