Let's divide 189861 by 49
We want to divide 189861 by 49.

Going ahead to step 1:
1 divided by 49 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 49

Moving on to step 2:
49 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 49

Advancing to step 3:
49 goes into 189 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 147 away from 189, we end up with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 49

Let's proceed to step 4:
If we divide 428 by 49, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 392 from 428 leaves us with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 49

Step 5:
49 goes into 366 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 387.0
Subtract 343 from 366 to get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 49

Going ahead to step 6:
49 goes into 231 4 times with a remainder of 35.
The next digit of our result is 4. 
Result so far: 3874.0
Deduct 196 from 231 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 49 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 3874.7
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
49 can be fit into 70 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 3874.71
Subtract 49 from 70 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
49 can be fit into 210 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 3874.714
If we subtract 196 from 210, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
49 goes into 140 2 times with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 3874.7142
Subtract 98 from 140 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 49 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 3874.71428
Deduct 392 from 420 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
49 can be fit into 280 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 3874.714285
Subtracting 245 from 280 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
49 can be fit into 350 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 3874.7142857
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
49 goes into 70 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 3874.71428571
Deduct 49 from 70 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 3874.71428571 and a remainder of 2.1e-08.
