Let's divide 10198209 by 159
The aim is to understand the frequency of 159 in 10198209.

Advancing to step 1:
159 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 159

Step 2:
When dividing 10 by 159, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 159

Let's proceed to step 3:
The number 159 fits into 101 0 times, leaving a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 101 leaves us with 101.
Fetch the next digit (9) from the dividend, attach it to 101 and continue: 1019 / 159

On to step 4:
The number 159 fits into 1019 6 times, leaving a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 954 from 1019 and we're left with 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 159

Moving on to step 5:
When dividing 658 by 159, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we take 636 away from 658, we end up with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 159

Let's proceed to step 6:
222 divided by 159 is 1 with a remainder of 63.
The next digit of our result is 1. 
Result so far: 641.0
Deduct 159 from 222 and we're left with 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 159

On to step 7:
159 goes into 630 3 times with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 6413.0
If we take 477 away from 630, we end up with 153.
Append the next digit (9) from the dividend to 153 and continue with: 1539 / 159

Advancing to step 8:
The number 159 fits into 1539 9 times, leaving a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 64139.0
The remainder is 108 after subtracting 1431 from 1539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
If we divide 1080 by 159, we get 6 and a remainder of 126.
Write down 6 as next digit of the result. 
Result so far: 64139.6
Deduct 954 from 1080 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 10:
159 goes into 1260 7 times with a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 64139.67
Subtracting 1113 from 1260 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 11:
159 can be fit into 1470 9 times, resulting in a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 64139.679
If we subtract 1431 from 1470, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
If we divide 390 by 159, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 64139.6792
Subtracting 318 from 390 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
If we divide 720 by 159, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 64139.67924
Subtract 636 from 720 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
The number 159 fits into 840 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 64139.679245
Subtract 795 from 840 to get 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 15:
159 goes into 450 2 times with a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 64139.6792452
If we subtract 318 from 450, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 16:
If we divide 1320 by 159, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 64139.67924528
Deduct 1272 from 1320 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 64139.67924528, with a leftover of 4.8e-08.
