42570517 ÷ 111 
We're looking to find how many times 111 goes into 42570517.

Advancing to step 1:
If we divide 4 by 111, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 111

Step 2:
111 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 111

Let's proceed to step 3:
If we divide 425 by 111, we get 3 and a remainder of 92.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 333 from 425 and we're left with 92.
Include the next digit (7) from the dividend after 92, then repeat: 927 / 111

Going ahead to step 4:
When dividing 927 by 111, we get 8 with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 39 after subtracting 888 from 927.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 111

Step 5:
When dividing 390 by 111, we get 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 383.0
If we subtract 333 from 390, we get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 111

Step 6:
111 goes into 575 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 3835.0
If we take 555 away from 575, we end up with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 111

Moving on to step 7:
111 goes into 201 1 times with a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 38351.0
The remainder is 90 after subtracting 111 from 201.
Include the next digit (7) from the dividend after 90, then repeat: 907 / 111

Let's proceed to step 8:
When dividing 907 by 111, we get 8 with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 383518.0
If we subtract 888 from 907, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
190 divided by 111 is 1 with a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 383518.1
If we subtract 111 from 190, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
790 divided by 111 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 383518.17
The remainder is 13 after subtracting 777 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
111 can be fit into 130 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 383518.171
If we take 111 away from 130, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
The number 111 fits into 190 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 383518.1711
If we take 111 away from 190, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 383518.1711, with a leftover of 0.00079.
