Let's divide 428887 by 30
We want to divide 428887 by 30.

Moving on to step 1:
If we divide 4 by 30, we get 0 and 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.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 30

On to step 2:
42 divided by 30 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 42 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 30

Advancing to step 3:
30 goes into 128 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 120 from 128 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 30

Going ahead to step 4:
The number 30 fits into 88 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 60 from 88 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 30

Advancing to step 5:
288 divided by 30 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1429.0
Subtract 270 from 288 to get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 30

Advancing to step 6:
The number 30 fits into 187 6 times, leaving a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 14296.0
Subtracting 180 from 187 leaves us 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.

Advancing to step 7:
70 divided by 30 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 14296.2
If we subtract 60 from 70, we 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.

Advancing to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 14296.23
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 14296.233
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 14296.233, with a leftover of 0.001.
