Let's divide 545807 by 42
We want to figure out the number of times 545807 can be divided by 42.

On to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 42

On to step 2:
42 goes into 54 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 54 and we're left with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 42

Going ahead to step 3:
42 goes into 125 2 times with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 84 from 125 and we're left with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 42

On to step 4:
The number 42 fits into 418 9 times, leaving a remainder of 40.
The next digit of our result is 9. 
Result so far: 129.0
The remainder is 40 after subtracting 378 from 418.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 42

Advancing to step 5:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 1299.0
Subtracting 378 from 400 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 42

Step 6:
When dividing 227 by 42, we get 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 12995.0
If we take 210 away from 227, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
42 can be fit into 170 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 12995.4
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 42, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12995.4
If we subtract 0 from 20, we 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.

Advancing to step 9:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 12995.404
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 10:
When dividing 320 by 42, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 12995.4047
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.

On to step 11:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 12995.40476
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.

Going ahead to step 12:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 12995.404761
Subtracting 42 from 80 leaves us 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 13:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 12995.4047619
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 14:
20 divided by 42 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12995.4047619
Subtracting 0 from 20 leaves us 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.

The final result is 12995.4047619 with a remainder of 2e-08.
