Let's divide 643847 by 49
We're looking to find how many times 49 goes into 643847.

Going ahead to step 1:
6 divided by 49 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 49

Moving on to step 2:
49 goes into 64 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 64 leaves us with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 49

Let's proceed to step 3:
153 divided by 49 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 147 from 153 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 49

Let's proceed to step 4:
68 divided by 49 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we subtract 49 from 68, we get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 49

Step 5:
When dividing 194 by 49, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 1313.0
The remainder is 47 after subtracting 147 from 194.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 49

Step 6:
477 divided by 49 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 13139.0
Deduct 441 from 477 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.

Moving on to step 7:
If we divide 360 by 49, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 13139.7
If we take 343 away from 360, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
49 goes into 170 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 13139.73
The remainder is 23 after subtracting 147 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
When dividing 230 by 49, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 13139.734
If we take 196 away from 230, we end up 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.

Going ahead to step 10:
49 can be fit into 340 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 13139.7346
If we subtract 294 from 340, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
When dividing 460 by 49, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 13139.73469
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
190 divided by 49 is 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 13139.734693
The remainder is 43 after subtracting 147 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
49 goes into 430 8 times with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 13139.7346938
The remainder is 38 after subtracting 392 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
When dividing 380 by 49, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 13139.73469387
If we take 343 away from 380, we end up 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.

In conclusion, the division gives 13139.73469387 with a balance of 3.7e-08.
