We're dividing 864138 by 49 
We want to divide 864138 by 49.

Going ahead to step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 49

Advancing to step 2:
86 divided by 49 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 49 away from 86, we end up with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 49

Let's proceed to step 3:
49 goes into 374 7 times with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 343 from 374 and we're left with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 49

On to step 4:
49 can be fit into 311 6 times, resulting in a remainder of 17.
The next digit of our result is 6. 
Result so far: 176.0
Subtract 294 from 311 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 49

Going ahead to step 5:
When dividing 173 by 49, we get 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 1763.0
Subtract 147 from 173 to get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 49

Step 6:
49 goes into 268 5 times with a remainder of 23.
The next digit of our result is 5. 
Result so far: 17635.0
Subtracting 245 from 268 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
230 divided by 49 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 17635.4
Deduct 196 from 230 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
340 divided by 49 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 17635.46
Deduct 294 from 340 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
49 can be fit into 460 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 17635.469
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
49 can be fit into 190 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 17635.4693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
The number 49 fits into 430 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 17635.46938
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
If we divide 380 by 49, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 17635.469387
Subtracting 343 from 380 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
If we divide 370 by 49, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 17635.4693877
Subtract 343 from 370 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 17635.4693877 with a remainder of 2.7e-07.
