We're dividing 834421 by 28 
We want to figure out the number of times 834421 can be divided by 28.

Advancing to step 1:
28 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 28

Going ahead to step 2:
When dividing 83 by 28, we get 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 56 away from 83, we end up with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 28

Moving on to step 3:
274 divided by 28 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 252 from 274 and we're left with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 28

Going ahead to step 4:
224 divided by 28 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 298.0
Subtract 224 from 224 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 28

Going ahead to step 5:
28 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 2980.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 28

Let's proceed to step 6:
21 divided by 28 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 29800.0
The remainder is 21 after subtracting 0 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
28 can be fit into 210 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 29800.7
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
28 goes into 140 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29800.75
If we subtract 140 from 140, 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.

Advancing to step 9:
28 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29800.75
Subtracting 0 from 0 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.

Advancing to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29800.75
Subtracting 0 from 0 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.

The final result is 29800.75 with a remainder of 0.0.
