Let's divide 70390 by 50
Let's see how many times 50 fits into 70390.

Step 1:
When dividing 7 by 50, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 50

Advancing to step 2:
50 goes into 70 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 50 from 70 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 50

Moving on to step 3:
50 can be fit into 203 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 200 away from 203, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 50

Step 4:
The number 50 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 50

Moving on to step 5:
390 divided by 50 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 1407.0
Deduct 350 from 390 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 6:
When dividing 400 by 50, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 1407.8
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 50, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1407.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 50, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1407.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 1407.8, and the remainder is 0.0.
