We're dividing 132371 by 42 
We want to figure out the number of times 132371 can be divided by 42.

On to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 42

Moving on to step 2:
13 divided by 42 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 42

Going ahead to step 3:
If we divide 132 by 42, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 126 from 132, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 42

Moving on to step 4:
If we divide 63 by 42, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 42 from 63 and we're left with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 42

Moving on to step 5:
42 can be fit into 217 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 315.0
The remainder is 7 after subtracting 210 from 217.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 42

Moving on to step 6:
42 can be fit into 71 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 3151.0
Subtracting 42 from 71 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
42 can be fit into 290 6 times, resulting in a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 3151.6
If we take 252 away from 290, 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.

Advancing to step 8:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3151.69
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.

Moving on to step 9:
20 divided by 42 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3151.69
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.

Going ahead to step 10:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 3151.6904
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.

Let's proceed to step 11:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 3151.69047
If we subtract 294 from 320, we get 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 12:
260 divided by 42 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 3151.690476
The remainder is 8 after subtracting 252 from 260.
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 13:
If we divide 80 by 42, we get 1 and a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 3151.6904761
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.

Step 14:
380 divided by 42 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 3151.69047619
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.

The final outcome is 3151.69047619, with a leftover of 2e-09.
