231840 ÷ 49 
We want to figure out the number of times 231840 can be divided by 49.

Going ahead to step 1:
The number 49 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 49

Going ahead to step 2:
23 divided by 49 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 49

Moving on to step 3:
The number 49 fits into 231 4 times, leaving a remainder of 35.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 35 after subtracting 196 from 231.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 49

On to step 4:
The number 49 fits into 358 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 343 from 358, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 49

Step 5:
154 divided by 49 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 473.0
Deduct 147 from 154 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 49

On to step 6:
If we divide 70 by 49, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 4731.0
Subtracting 49 from 70 leaves us 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.

On to step 7:
When dividing 210 by 49, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4731.4
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.

Step 8:
When dividing 140 by 49, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 4731.42
If we take 98 away from 140, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 49, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 4731.428
The remainder is 28 after subtracting 392 from 420.
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 10:
49 can be fit into 280 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4731.4285
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 11:
The number 49 fits into 350 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 4731.42857
The remainder is 7 after subtracting 343 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
70 divided by 49 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 4731.428571
Subtracting 49 from 70 leaves us 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.

Going ahead to step 13:
49 goes into 210 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4731.4285714
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
140 divided by 49 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 4731.42857142
Deduct 98 from 140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 4731.42857142, with a leftover of 4.2e-08.
