We look at the division of 11211705 by 157 
The aim is to understand the frequency of 157 in 11211705.

Moving on to step 1:
157 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 157

Going ahead to step 2:
11 divided by 157 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 157

On to step 3:
157 goes into 112 0 times with a remainder of 112.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 112 and we're left with 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 157

Moving on to step 4:
1121 divided by 157 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 1099 from 1121 and we're left with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 157

Let's proceed to step 5:
When dividing 221 by 157, we get 1 with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtracting 157 from 221 leaves us with 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 157

Let's proceed to step 6:
647 divided by 157 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 714.0
If we take 628 away from 647, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 157

Moving on to step 7:
157 goes into 190 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 7141.0
If we subtract 157 from 190, we get 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 157

Step 8:
If we divide 335 by 157, we get 2 and a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 71412.0
Subtracting 314 from 335 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
157 goes into 210 1 times with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 71412.1
The remainder is 53 after subtracting 157 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 10:
157 goes into 530 3 times with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 71412.13
Subtract 471 from 530 to 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.

Advancing to step 11:
If we divide 590 by 157, we get 3 and a remainder of 119.
The number 3 becomes the next digit in our result. 
Result so far: 71412.133
The remainder is 119 after subtracting 471 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

After the division, we end up with 71412.133 and a remainder of 0.0119.
