886457 divided by 42 
We want to figure out the number of times 886457 can be divided by 42.

Moving on to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 42

Advancing to step 2:
42 goes into 88 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 84 from 88 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 42

On to step 3:
If we divide 46 by 42, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 42 from 46 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 42

Advancing to step 4:
When dividing 44 by 42, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 211.0
The remainder is 2 after subtracting 42 from 44.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

Advancing to step 5:
When dividing 25 by 42, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 2110.0
If we subtract 0 from 25, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 42

Going ahead to step 6:
42 goes into 257 6 times with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 21106.0
Deduct 252 from 257 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 42, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 21106.1
Subtract 42 from 50 to get 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 8:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 21106.11
If we take 42 away from 80, we end up 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.

The final outcome is 21106.11, with a leftover of 0.038.
