151313 divided by 42 
We want to figure out the number of times 151313 can be divided by 42.

Going ahead to step 1:
1 divided by 42 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 42

Advancing to step 2:
15 divided by 42 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 42

Going ahead to step 3:
42 goes into 151 3 times with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 25 after subtracting 126 from 151.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 42

Advancing to step 4:
42 can be fit into 253 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 1 after subtracting 252 from 253.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 42

On to step 5:
11 divided by 42 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 42

Let's proceed to step 6:
42 can be fit into 113 2 times, resulting in a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 3602.0
If we subtract 84 from 113, we get 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:
290 divided by 42 is 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 3602.6
The remainder is 38 after subtracting 252 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
When dividing 380 by 42, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 3602.69
The remainder is 2 after subtracting 378 from 380.
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:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3602.69
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.

On to step 10:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 3602.6904
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.

Going ahead to step 11:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 3602.69047
Subtracting 294 from 320 leaves us 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 12:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 3602.690476
If we subtract 252 from 260, we 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.

On to step 13:
42 goes into 80 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 3602.6904761
If we subtract 42 from 80, we 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.

Let's proceed to step 14:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3602.69047619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 3602.69047619 with a remaining 2e-09.
