We're dividing 68106928 by 291 
The aim is to understand the frequency of 291 in 68106928.

Step 1:
291 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 291

Advancing to step 2:
When dividing 68 by 291, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 291

Advancing to step 3:
291 goes into 681 2 times with a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 582 from 681, we get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 291

Step 4:
291 goes into 990 3 times with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 873 from 990 to get 117.
Bring next digit (6) of the dividend behind the 117 and repeat the process: 1176 / 291

Going ahead to step 5:
If we divide 1176 by 291, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 234.0
Subtracting 1164 from 1176 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 291

Moving on to step 6:
The number 291 fits into 129 0 times, leaving a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 2340.0
If we take 0 away from 129, we end up with 129.
Take the next digit (2) from the dividend and append it to 129, then repeat: 1292 / 291

Step 7:
When dividing 1292 by 291, we get 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 23404.0
The remainder is 128 after subtracting 1164 from 1292.
Take the next digit (8) from the dividend and append it to 128, then repeat: 1288 / 291

On to step 8:
291 goes into 1288 4 times with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 234044.0
If we take 1164 away from 1288, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
The number 291 fits into 1240 4 times, leaving a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 234044.4
Subtracting 1164 from 1240 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 291 is 2 with a remainder of 178.
The next digit of our result is 2. 
Result so far: 234044.42
If we subtract 582 from 760, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 11:
If we divide 1780 by 291, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 234044.426
Subtracting 1746 from 1780 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
340 divided by 291 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 234044.4261
Subtract 291 from 340 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 13:
490 divided by 291 is 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 234044.42611
Deduct 291 from 490 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 234044.42611 and a remainder of 0.000199.
