We divide 191321 by 42
We want to figure out the number of times 191321 can be divided by 42.

Step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 42

Advancing to step 2:
If we divide 19 by 42, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 42

Let's proceed to step 3:
If we divide 191 by 42, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 23 after subtracting 168 from 191.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 42

Going ahead to step 4:
If we divide 233 by 42, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 23 after subtracting 210 from 233.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 42

On to step 5:
42 can be fit into 232 5 times, resulting in a remainder of 22.
The next digit of our result is 5. 
Result so far: 455.0
The remainder is 22 after subtracting 210 from 232.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 42

Moving on to step 6:
42 can be fit into 221 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 4555.0
If we subtract 210 from 221, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
If we divide 110 by 42, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 4555.2
If we take 84 away from 110, we end up 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.

Advancing to step 8:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 4555.26
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 4555.261
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 4555.2619
If we take 378 away from 380, we end up 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 11:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4555.2619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 42 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 4555.261904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 4555.2619047
If we take 294 away from 320, we end up 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.

Going ahead to step 14:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4555.26190476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 4555.26190476 with a remaining 8e-09.
