478085 ÷ 42 
We want to divide 478085 by 42.

On to step 1:
4 divided by 42 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 42

Going ahead to step 2:
If we divide 47 by 42, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 47 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 42

On to step 3:
42 can be fit into 58 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 42 away from 58, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 42

Let's proceed to step 4:
160 divided by 42 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Deduct 126 from 160 and we're left with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 42

On to step 5:
When dividing 348 by 42, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 1138.0
Subtracting 336 from 348 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 42

Step 6:
The number 42 fits into 125 2 times, leaving a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 11382.0
If we take 84 away from 125, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
The number 42 fits into 410 9 times, leaving a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 11382.9
The remainder is 32 after subtracting 378 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 11382.97
Subtracting 294 from 320 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.

Let's proceed to step 9:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11382.976
Subtracting 252 from 260 leaves us 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 10:
If we divide 80 by 42, we get 1 and a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 11382.9761
Deduct 42 from 80 and we're left 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.

Going ahead to step 11:
42 goes into 380 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 11382.97619
Subtracting 378 from 380 leaves us 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.

Advancing to step 12:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11382.97619
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.

Moving on to step 13:
If we divide 200 by 42, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 11382.9761904
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.

Going ahead to step 14:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 11382.97619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 11382.97619047, with a leftover of 2.6e-08.
