Let's divide 122591 by 28
We're looking to find how many times 28 goes into 122591.

Let's proceed to step 1:
1 divided by 28 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 28

Advancing to step 2:
The number 28 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 28

Moving on to step 3:
28 goes into 122 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 112 away from 122, we end up with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 28

Moving on to step 4:
28 goes into 105 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 84 from 105 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 28

Advancing to step 5:
28 goes into 219 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 437.0
The remainder is 23 after subtracting 196 from 219.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 28

Advancing to step 6:
The number 28 fits into 231 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 4378.0
Deduct 224 from 231 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 28, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 4378.2
If we take 56 away from 70, we end up 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.

Step 8:
If we divide 140 by 28, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4378.25
Subtract 140 from 140 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.

Step 9:
When dividing 0 by 28, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4378.25
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.

Going ahead to step 10:
When dividing 0 by 28, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4378.25
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.

Our division results in 4378.25 with a remaining 0.0.
