307535 ÷ 42 
We want to figure out the number of times 307535 can be divided by 42.

On to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Let's proceed to step 2:
42 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 42

Moving on to step 3:
307 divided by 42 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 294 from 307, we get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 42

Moving on to step 4:
42 can be fit into 135 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtract 126 from 135 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 42

Step 5:
If we divide 93 by 42, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 732.0
Subtracting 84 from 93 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 42

Going ahead to step 6:
42 can be fit into 95 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 7322.0
The remainder is 11 after subtracting 84 from 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 42, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 7322.2
The remainder is 26 after subtracting 84 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
42 goes into 260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 7322.26
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.

Advancing to step 9:
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: 7322.261
Deduct 42 from 80 and we're left 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 10:
The number 42 fits into 380 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 7322.2619
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.

Let's proceed to step 11:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7322.2619
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.

Let's proceed to step 12:
If we divide 200 by 42, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 7322.261904
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.

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: 7322.2619047
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.

Advancing to step 14:
When dividing 260 by 42, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7322.26190476
If we take 252 away from 260, we end up 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.

The final outcome is 7322.26190476, with a leftover of 8e-09.
