We're dividing 551199 by 42 
We're looking to find how many times 42 goes into 551199.

Going ahead to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 42

Going ahead to step 2:
55 divided by 42 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 13 after subtracting 42 from 55.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 42

Let's proceed to step 3:
42 goes into 131 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 126 away from 131, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 42

On to step 4:
42 can be fit into 51 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 131.0
The remainder is 9 after subtracting 42 from 51.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 42

Advancing to step 5:
42 can be fit into 99 2 times, resulting in a remainder of 15.
The next digit of our result is 2. 
Result so far: 1312.0
Subtract 84 from 99 to get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 42

Going ahead to step 6:
The number 42 fits into 159 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 13123.0
If we subtract 126 from 159, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
The number 42 fits into 330 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 13123.7
Subtract 294 from 330 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 13123.78
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
42 goes into 240 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 13123.785
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 13123.7857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 13123.78571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 13123.785714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 13123.7857142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 13123.78571428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 13123.78571428, with a leftover of 2.4e-08.
