We look at the division of 71255426 by 156 
The aim is to understand the frequency of 156 in 71255426.

Step 1:
When dividing 7 by 156, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 156

Advancing to step 2:
If we divide 71 by 156, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 156

Going ahead to step 3:
The number 156 fits into 712 4 times, leaving a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 624 from 712 and we're left with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 156

Advancing to step 4:
If we divide 885 by 156, we get 5 and a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 780 from 885, we get 105.
Include the next digit (5) from the dividend after 105, then repeat: 1055 / 156

Going ahead to step 5:
If we divide 1055 by 156, we get 6 and a remainder of 119.
The next digit of our result is 6. 
Result so far: 456.0
The remainder is 119 after subtracting 936 from 1055.
Grab the next digit (4) from the dividend, add it to 119, then carry on: 1194 / 156

Moving on to step 6:
1194 divided by 156 is 7 with a remainder of 102.
Write down 7 as next digit of the result. 
Result so far: 4567.0
If we take 1092 away from 1194, we end up with 102.
Take the next digit (2) from the dividend and append it to 102, then repeat: 1022 / 156

On to step 7:
When dividing 1022 by 156, we get 6 with a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 45676.0
If we subtract 936 from 1022, we get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 156

Advancing to step 8:
When dividing 866 by 156, we get 5 with a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 456765.0
If we take 780 away from 866, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
If we divide 860 by 156, we get 5 and a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 456765.5
The remainder is 80 after subtracting 780 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
156 goes into 800 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 456765.55
Subtract 780 from 800 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 456765.55, and the remainder is 0.02.
