We divide 621930 by 49
We want to figure out the number of times 621930 can be divided by 49.

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
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 49

Step 2:
When dividing 62 by 49, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 49 away from 62, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 49

Advancing to step 3:
If we divide 131 by 49, we get 2 and a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 98 from 131, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 49

Advancing to step 4:
339 divided by 49 is 6 with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we subtract 294 from 339, we get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 49

On to step 5:
If we divide 453 by 49, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 1269.0
Subtract 441 from 453 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 49

Advancing to step 6:
49 goes into 120 2 times with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 12692.0
Deduct 98 from 120 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
220 divided by 49 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 12692.4
Deduct 196 from 220 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
49 goes into 240 4 times with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 12692.44
If we subtract 196 from 240, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 12692.44 with a remainder of 0.044.
