553207 ÷ 42 
We want to figure out the number of times 553207 can be divided by 42.

Let's proceed to step 1:
42 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 42

Going ahead to step 2:
The number 42 fits into 55 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 55 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 42

On to step 3:
The number 42 fits into 133 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 126 from 133 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 42

Going ahead to step 4:
The number 42 fits into 72 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 131.0
If we take 42 away from 72, we end up with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 42

Step 5:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1317.0
Subtracting 294 from 300 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 42

On to step 6:
42 can be fit into 67 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 13171.0
If we take 42 away from 67, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
42 goes into 250 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 13171.5
Subtracting 210 from 250 leaves us 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.

Step 8:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 13171.59
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 42, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13171.595
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 10:
When dividing 100 by 42, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 13171.5952
Subtract 84 from 100 to get 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 11:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13171.59523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
If we divide 340 by 42, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 13171.595238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
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: 13171.595238
If we subtract 0 from 40, we get 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 14:
400 divided by 42 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 13171.59523809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 13171.59523809 with a remainder of 2.2e-08.
