186715 ÷ 42 
Our goal is to divide 186715 by 42.

Going ahead to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 42

Going ahead to step 2:
42 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 42

Moving on to step 3:
If we divide 186 by 42, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 168 from 186 to get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 42

Let's proceed to step 4:
The number 42 fits into 187 4 times, leaving a remainder of 19.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 19 after subtracting 168 from 187.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 42

Step 5:
191 divided by 42 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 444.0
If we take 168 away from 191, we end up with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 42

Moving on to step 6:
42 can be fit into 235 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4445.0
If we subtract 210 from 235, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
If we divide 250 by 42, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 4445.5
Subtract 210 from 250 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 42, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 4445.59
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 4445.595
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 42 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 4445.5952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 42 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 4445.59523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4445.595238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4445.595238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
42 goes into 400 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 4445.59523809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 4445.59523809, with a leftover of 2.2e-08.
