We look at the division of 79647828 by 155 
The aim is to understand the frequency of 155 in 79647828.

On to step 1:
155 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 155

Moving on to step 2:
When dividing 79 by 155, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Bring next digit (6) of the dividend behind the 79 and repeat the process: 796 / 155

Let's proceed to step 3:
If we divide 796 by 155, we get 5 and a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 775 away from 796, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 155

Going ahead to step 4:
When dividing 214 by 155, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Deduct 155 from 214 and we're left with 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 155

Moving on to step 5:
155 goes into 597 3 times with a remainder of 132.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
Subtracting 465 from 597 leaves us with 132.
Bring next digit (8) of the dividend behind the 132 and repeat the process: 1328 / 155

Step 6:
If we divide 1328 by 155, we get 8 and a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 5138.0
The remainder is 88 after subtracting 1240 from 1328.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 155

Moving on to step 7:
The number 155 fits into 882 5 times, leaving a remainder of 107.
Put 5 as the next digit of the answer. 
Result so far: 51385.0
The remainder is 107 after subtracting 775 from 882.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 155

Going ahead to step 8:
1078 divided by 155 is 6 with a remainder of 148.
The next digit of our result is 6. 
Result so far: 513856.0
If we subtract 930 from 1078, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 9:
155 can be fit into 1480 9 times, resulting in a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 513856.9
Deduct 1395 from 1480 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
155 can be fit into 850 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 513856.95
Subtracting 775 from 850 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
750 divided by 155 is 4 with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 513856.954
The remainder is 130 after subtracting 620 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 12:
The number 155 fits into 1300 8 times, leaving a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 513856.9548
The remainder is 60 after subtracting 1240 from 1300.
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 13:
155 goes into 600 3 times with a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 513856.95483
Subtracting 465 from 600 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 14:
When dividing 1350 by 155, we get 8 with a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 513856.954838
Deduct 1240 from 1350 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
When dividing 1100 by 155, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 513856.9548387
If we subtract 1085 from 1100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 16:
The number 155 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 513856.9548387
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 513856.9548387, with a leftover of 1.5e-07.
