42458112 divided by 102 
Let's see how many times 102 fits into 42458112.

Step 1:
If we divide 4 by 102, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 102

Advancing to step 2:
When dividing 42 by 102, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 102

Step 3:
102 goes into 424 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 408 from 424 and we're left with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 102

Step 4:
If we divide 165 by 102, we get 1 and a remainder of 63.
The next digit of our result is 1. 
Result so far: 41.0
If we take 102 away from 165, we end up with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 102

Moving on to step 5:
638 divided by 102 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
If we subtract 612 from 638, we get 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 102

Going ahead to step 6:
261 divided by 102 is 2 with a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 4162.0
Deduct 204 from 261 and we're left with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 102

On to step 7:
102 can be fit into 571 5 times, resulting in a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 41625.0
Deduct 510 from 571 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 102

Step 8:
When dividing 612 by 102, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 416256.0
The remainder is 0 after subtracting 612 from 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 102, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 416256.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 102, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 416256.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 416256.0, with a leftover of 0.0.
