644190 ÷ 49 
We want to divide 644190 by 49.

Going ahead to step 1:
6 divided by 49 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 49

Let's proceed to step 2:
If we divide 64 by 49, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 49 away from 64, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 49

Going ahead to step 3:
The number 49 fits into 154 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 7 after subtracting 147 from 154.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 49

Going ahead to step 4:
49 can be fit into 71 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we subtract 49 from 71, we get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 49

Step 5:
49 can be fit into 229 4 times, resulting in a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 1314.0
The remainder is 33 after subtracting 196 from 229.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 49

Step 6:
49 goes into 330 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 13146.0
Deduct 294 from 330 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.

On to step 7:
49 can be fit into 360 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 13146.7
Subtracting 343 from 360 leaves us 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.

Step 8:
When dividing 170 by 49, we get 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 13146.73
If we take 147 away from 170, we end up 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 9:
If we divide 230 by 49, we get 4 and a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 13146.734
If we subtract 196 from 230, 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.

On to step 10:
The number 49 fits into 340 6 times, leaving a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 13146.7346
If we take 294 away from 340, we end up 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.

Moving on to step 11:
49 goes into 460 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 13146.73469
If we subtract 441 from 460, we get 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 12:
190 divided by 49 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 13146.734693
Subtract 147 from 190 to 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.

Moving on to step 13:
430 divided by 49 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 13146.7346938
Subtract 392 from 430 to get 38.
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:
49 goes into 380 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 13146.73469387
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.

The final result is 13146.73469387 with a remainder of 3.7e-08.
