We look at the division of 392189 by 50 
We're looking to find how many times 50 goes into 392189.

Moving on to step 1:
The number 50 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 50

Advancing to step 2:
The number 50 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 50

Moving on to step 3:
If we divide 392 by 50, we get 7 and a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 42 after subtracting 350 from 392.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 50

Moving on to step 4:
50 can be fit into 421 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 400 away from 421, we end up with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 50

On to step 5:
218 divided by 50 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Subtract 200 from 218 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 50

Moving on to step 6:
50 goes into 189 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 7843.0
If we take 150 away from 189, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 50 fits into 390 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 7843.7
Subtract 350 from 390 to get 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 8:
If we divide 400 by 50, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 7843.78
Subtracting 400 from 400 leaves us with 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 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7843.78
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7843.78
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 final outcome is 7843.78, with a leftover of 0.0.
