921138 ÷ 50 
Our goal is to divide 921138 by 50.

On to step 1:
9 divided by 50 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 50

Let's proceed to step 2:
50 can be fit into 92 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 50 from 92, we get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 50

Advancing to step 3:
If we divide 421 by 50, we get 8 and a remainder of 21.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 400 from 421 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 50

On to step 4:
When dividing 211 by 50, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 184.0
Subtracting 200 from 211 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 50

Step 5:
The number 50 fits into 113 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 1842.0
Subtract 100 from 113 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 50

Let's proceed to step 6:
The number 50 fits into 138 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 18422.0
If we take 100 away from 138, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
50 can be fit into 380 7 times, resulting in a remainder of 30.
The next digit of our result is 7. 
Result so far: 18422.7
Deduct 350 from 380 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
50 can be fit into 300 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 18422.76
Deduct 300 from 300 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.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18422.76
If we take 0 away from 0, we end up 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:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18422.76
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.

The final result is 18422.76 with a remainder of 0.0.
