130523 ÷ 42 
We want to divide 130523 by 42.

Going ahead to step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 42

Let's proceed to step 2:
42 goes into 13 0 times 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.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 42

On to step 3:
If we divide 130 by 42, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 4 after subtracting 126 from 130.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 42

Advancing to step 4:
The number 42 fits into 45 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 42 from 45 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 42

Advancing to step 5:
42 goes into 32 0 times with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 310.0
Subtracting 0 from 32 leaves us with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 42

Advancing to step 6:
If we divide 323 by 42, we get 7 and a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 3107.0
Subtracting 294 from 323 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.

On to step 7:
The number 42 fits into 290 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 3107.6
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.

Step 8:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 3107.69
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:
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: 3107.69
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:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3107.6904
Subtract 168 from 200 to get 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 11:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 3107.69047
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.

Advancing to step 12:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3107.690476
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.

Moving on to step 13:
80 divided by 42 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 3107.6904761
The remainder is 38 after subtracting 42 from 80.
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 14:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 3107.69047619
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.

The final outcome is 3107.69047619, with a leftover of 2e-09.
