We're dividing 646738 by 49 
We want to figure out the number of times 646738 can be divided by 49.

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
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 49

Advancing to step 2:
49 can be fit into 64 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 49 from 64, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 49

Advancing to step 3:
49 goes into 156 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 147 from 156 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 49

Let's proceed to step 4:
The number 49 fits into 97 1 times, leaving a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 131.0
The remainder is 48 after subtracting 49 from 97.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 49

Moving on to step 5:
The number 49 fits into 483 9 times, leaving a remainder of 42.
The next digit of our result is 9. 
Result so far: 1319.0
If we take 441 away from 483, we end up with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 49

On to step 6:
When dividing 428 by 49, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 13198.0
Subtracting 392 from 428 leaves us 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.

Advancing to step 7:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 13198.7
If we subtract 343 from 360, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
When dividing 170 by 49, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 13198.73
Subtracting 147 from 170 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 9:
49 can be fit into 230 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 13198.734
Subtracting 196 from 230 leaves us 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.

Advancing to step 10:
When dividing 340 by 49, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 13198.7346
The remainder is 46 after subtracting 294 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
If we divide 460 by 49, we get 9 and a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 13198.73469
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.

Going ahead to step 12:
49 goes into 190 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 13198.734693
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.

Going ahead to step 13:
49 goes into 430 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 13198.7346938
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.

Advancing to step 14:
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: 13198.73469387
If we subtract 343 from 380, we get 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 13198.73469387 with a balance of 3.7e-08.
