We divide 2159822 by 141
The aim is to understand the frequency of 141 in 2159822.

Step 1:
If we divide 2 by 141, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 141

Going ahead to step 2:
The number 141 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 141

Advancing to step 3:
141 can be fit into 215 1 times, resulting in a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 141 away from 215, we end up with 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 141

Moving on to step 4:
749 divided by 141 is 5 with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 705 from 749 and we're left with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 141

Step 5:
If we divide 448 by 141, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 423 from 448 to get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 141

Let's proceed to step 6:
If we divide 252 by 141, we get 1 and a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 1531.0
Subtracting 141 from 252 leaves us with 111.
Grab the next digit (2) from the dividend, add it to 111, then carry on: 1112 / 141

Going ahead to step 7:
141 goes into 1112 7 times with a remainder of 125.
Write down 7 as next digit of the result. 
Result so far: 15317.0
Subtract 987 from 1112 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 8:
When dividing 1250 by 141, we get 8 with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 15317.8
The remainder is 122 after subtracting 1128 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
141 goes into 1220 8 times with a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 15317.88
If we subtract 1128 from 1220, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 15317.88 with a remainder of 0.092.
