Let's divide 187631 by 42
The aim is to understand the frequency of 42 in 187631.

On to step 1:
1 divided by 42 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 42

On to step 2:
If we divide 18 by 42, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 42

Advancing to step 3:
42 goes into 187 4 times with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 19 after subtracting 168 from 187.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 42

Step 4:
42 goes into 196 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 168 from 196 leaves us with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 42

Step 5:
The number 42 fits into 283 6 times, leaving a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 446.0
If we subtract 252 from 283, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 42

Moving on to step 6:
42 can be fit into 311 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 4467.0
If we subtract 294 from 311, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
When dividing 170 by 42, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4467.4
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4467.4
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 42, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4467.404
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 4467.4047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4467.40476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 4467.404761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
If we divide 380 by 42, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 4467.4047619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4467.4047619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 4467.4047619 with a balance of 2e-08.
