We're dividing 186906 by 42 
Let's see how many times 42 fits into 186906.

Let's proceed to step 1:
42 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 42

On to step 2:
18 divided by 42 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
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

On to step 3:
42 goes into 186 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 168 from 186 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 42

Moving on to step 4:
189 divided by 42 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 168 from 189 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 42

Going ahead to step 5:
210 divided by 42 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 445.0
Subtract 210 from 210 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 42

On to step 6:
6 divided by 42 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 4450.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4450.1
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4450.14
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 4450.142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 4450.1428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4450.14285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
When dividing 300 by 42, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 4450.142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
42 goes into 60 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 4450.1428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4450.14285714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 4450.14285714 with a balance of 1.2e-08.
