We're dividing 366503 by 42 
We're looking to find how many times 42 goes into 366503.

Let's proceed to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 42

On to step 2:
36 divided by 42 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 42

On to step 3:
When dividing 366 by 42, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 336 from 366, we get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 42

Going ahead to step 4:
42 goes into 305 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 87.0
The remainder is 11 after subtracting 294 from 305.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 42

On to step 5:
The number 42 fits into 110 2 times, leaving a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 872.0
Subtracting 84 from 110 leaves us with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 42

Let's proceed to step 6:
42 goes into 263 6 times with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 8726.0
Deduct 252 from 263 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
If we divide 110 by 42, we get 2 and a remainder of 26.
The next digit of our result is 2. 
Result so far: 8726.2
Subtracting 84 from 110 leaves us 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.

Going ahead to step 8:
260 divided by 42 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 8726.26
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.

Step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 8726.261
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
42 goes into 380 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 8726.2619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8726.2619
Deduct 0 from 20 and we're left 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:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 8726.261904
The remainder is 32 after subtracting 168 from 200.
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.
Use 7 as the next digit of our solution. 
Result so far: 8726.2619047
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.

On to step 14:
If we divide 260 by 42, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8726.26190476
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.

Our division results in 8726.26190476 with a remaining 8e-09.
