We look at the division of 6777755 by 159 
The aim is to understand the frequency of 159 in 6777755.

On to step 1:
159 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 159

Step 2:
159 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (7) from the dividend, add it to 67, then carry on: 677 / 159

Advancing to step 3:
159 can be fit into 677 4 times, resulting in a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 636 from 677 to get 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 159

Going ahead to step 4:
159 goes into 417 2 times with a remainder of 99.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 318 from 417 leaves us with 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 159

Moving on to step 5:
159 can be fit into 997 6 times, resulting in a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 426.0
If we take 954 away from 997, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 159

Moving on to step 6:
If we divide 435 by 159, we get 2 and a remainder of 117.
Put 2 as the next digit of the answer. 
Result so far: 4262.0
The remainder is 117 after subtracting 318 from 435.
Grab the next digit (5) from the dividend, add it to 117, then carry on: 1175 / 159

Advancing to step 7:
When dividing 1175 by 159, we get 7 with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 42627.0
Deduct 1113 from 1175 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
159 goes into 620 3 times with a remainder of 143.
Use 3 as the next digit of our solution. 
Result so far: 42627.3
Subtracting 477 from 620 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
The number 159 fits into 1430 8 times, leaving a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 42627.38
Subtracting 1272 from 1430 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 10:
If we divide 1580 by 159, we get 9 and a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 42627.389
Deduct 1431 from 1580 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 11:
When dividing 1490 by 159, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 42627.3899
If we subtract 1431 from 1490, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 42627.3899 with a remaining 0.00059.
