Let's divide 136807 by 42
We're looking to find how many times 42 goes into 136807.

On to step 1:
42 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 42

Step 2:
The number 42 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 42

Step 3:
136 divided by 42 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 126 from 136 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 42

On to step 4:
108 divided by 42 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 24 after subtracting 84 from 108.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 42

Going ahead to step 5:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 325.0
Deduct 210 from 240 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 42

Step 6:
42 can be fit into 307 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 3257.0
Subtract 294 from 307 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 42 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3257.3
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 3257.3
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 3257.309
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
When dividing 220 by 42, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3257.3095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 42, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3257.30952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 42 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3257.309523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
42 goes into 340 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 3257.3095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3257.3095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 3257.3095238 and a remainder of 4e-08.
