We look at the division of 68209620 by 157 
The aim is to understand the frequency of 157 in 68209620.

Let's proceed to step 1:
The number 157 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 157

Moving on to step 2:
157 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 157

On to step 3:
157 goes into 682 4 times with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 54 after subtracting 628 from 682.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 157

Advancing to step 4:
157 can be fit into 540 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 471 away from 540, we end up with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 157

Step 5:
699 divided by 157 is 4 with a remainder of 71.
The next digit of our result is 4. 
Result so far: 434.0
Subtract 628 from 699 to get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 157

On to step 6:
716 divided by 157 is 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 4344.0
Subtracting 628 from 716 leaves us with 88.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 157

Going ahead to step 7:
157 can be fit into 882 5 times, resulting in a remainder of 97.
Use 5 as the next digit of our solution. 
Result so far: 43445.0
Subtracting 785 from 882 leaves us with 97.
Bring next digit (0) of the dividend behind the 97 and repeat the process: 970 / 157

Advancing to step 8:
When dividing 970 by 157, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 434456.0
If we subtract 942 from 970, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
157 can be fit into 280 1 times, resulting in a remainder of 123.
The next digit of our result is 1. 
Result so far: 434456.1
If we take 157 away from 280, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 10:
1230 divided by 157 is 7 with a remainder of 131.
The number 7 becomes the next digit in our result. 
Result so far: 434456.17
Subtracting 1099 from 1230 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 11:
1310 divided by 157 is 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 434456.178
The remainder is 54 after subtracting 1256 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
157 goes into 540 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 434456.1783
If we subtract 471 from 540, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 13:
If we divide 690 by 157, we get 4 and a remainder of 62.
The next digit of our result is 4. 
Result so far: 434456.17834
Subtracting 628 from 690 leaves us 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.

Advancing to step 14:
620 divided by 157 is 3 with a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 434456.178343
Deduct 471 from 620 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.

Moving on to step 15:
157 can be fit into 1490 9 times, resulting in a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 434456.1783439
Subtracting 1413 from 1490 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 16:
157 can be fit into 770 4 times, resulting in a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 434456.17834394
The remainder is 142 after subtracting 628 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 434456.17834394 with a remainder of 1.42e-07.
