Let's divide 430930 by 28
We want to divide 430930 by 28.

Step 1:
28 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 28

On to step 2:
28 goes into 43 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 28 from 43 leaves us with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 28

On to step 3:
28 goes into 150 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 140 away from 150, we end up with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 28

On to step 4:
The number 28 fits into 109 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtract 84 from 109 to get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 28

Step 5:
28 goes into 253 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1539.0
If we take 252 away from 253, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 28

Advancing to step 6:
The number 28 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15390.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 28, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 15390.3
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 15390.35
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 15390.357
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 15390.3571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 15390.35714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 15390.357142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 15390.3571428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15390.35714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 15390.35714285, with a leftover of 2e-08.
