We look at the division of 81562230 by 157 
The aim is to understand the frequency of 157 in 81562230.

Moving on to step 1:
If we divide 8 by 157, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 157

Advancing to step 2:
157 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 157

Let's proceed to step 3:
The number 157 fits into 815 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 30 after subtracting 785 from 815.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 157

Going ahead to step 4:
The number 157 fits into 306 1 times, leaving a remainder of 149.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 157 from 306 and we're left with 149.
Take the next digit (2) from the dividend and append it to 149, then repeat: 1492 / 157

Going ahead to step 5:
157 goes into 1492 9 times with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
Deduct 1413 from 1492 and we're left with 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 157

Let's proceed to step 6:
792 divided by 157 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 5195.0
Deduct 785 from 792 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 157

Let's proceed to step 7:
73 divided by 157 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 51950.0
If we take 0 away from 73, we end up with 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 157

Moving on to step 8:
When dividing 730 by 157, we get 4 with a remainder of 102.
Put 4 as the next digit of the answer. 
Result so far: 519504.0
If we take 628 away from 730, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
157 can be fit into 1020 6 times, resulting in a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 519504.6
The remainder is 78 after subtracting 942 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
If we divide 780 by 157, we get 4 and a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 519504.64
The remainder is 152 after subtracting 628 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
The number 157 fits into 1520 9 times, leaving a remainder of 107.
Put 9 as the next digit of the answer. 
Result so far: 519504.649
If we subtract 1413 from 1520, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 12:
If we divide 1070 by 157, we get 6 and a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 519504.6496
The remainder is 128 after subtracting 942 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 13:
If we divide 1280 by 157, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 519504.64968
Subtract 1256 from 1280 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
157 can be fit into 240 1 times, resulting in a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 519504.649681
Deduct 157 from 240 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 15:
The number 157 fits into 830 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 519504.6496815
Deduct 785 from 830 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 16:
When dividing 450 by 157, we get 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 519504.64968152
If we subtract 314 from 450, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 519504.64968152 and a remainder of 1.36e-07.
