We look at the division of 187770 by 42 
Let's see how many times 42 fits into 187770.

Step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 42

Going ahead to step 2:
The number 42 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 42

Let's proceed to step 3:
187 divided by 42 is 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 168 from 187 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 42

Advancing to step 4:
The number 42 fits into 197 4 times, leaving a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 168 from 197 and we're left with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 42

Moving on to step 5:
If we divide 297 by 42, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 447.0
Subtracting 294 from 297 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Going ahead to step 6:
When dividing 30 by 42, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4470.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 4470.7
If we take 294 away from 300, we end up with 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 8:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4470.71
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 42, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4470.714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 4470.7142
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 11:
360 divided by 42 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4470.71428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
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: 4470.714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 4470.7142857
If we subtract 294 from 300, 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 14:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 4470.71428571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 4470.71428571, and the remainder is 1.8e-08.
