We're dividing 187738 by 42 
Let's see how many times 42 fits into 187738.

Going ahead to step 1:
42 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 42

On to step 2:
If we divide 18 by 42, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 42

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

Going ahead to step 4:
42 goes into 197 4 times with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 168 from 197 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 42

Advancing to step 5:
The number 42 fits into 293 6 times, leaving a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 446.0
Subtract 252 from 293 to get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 42

Step 6:
42 can be fit into 418 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 4469.0
Subtracting 378 from 418 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 4469.9
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.

On to step 8:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 4469.95
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.

Step 9:
If we divide 100 by 42, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4469.952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 4469.9523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 4469.95238
If we subtract 336 from 340, we 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.

On to step 12:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4469.95238
Deduct 0 from 40 and we're left with 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 13:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 4469.9523809
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.

Let's proceed to step 14:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4469.95238095
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.

Our division results in 4469.95238095 with a remaining 1e-08.
