We look at the division of 21382153 by 284 
We want to divide 21382153 by 284.

Let's proceed to step 1:
284 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 284

Moving on to step 2:
284 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 284

Let's proceed to step 3:
284 can be fit into 213 0 times, resulting in a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Grab the next digit (8) from the dividend, add it to 213, then carry on: 2138 / 284

Let's proceed to step 4:
If we divide 2138 by 284, we get 7 and a remainder of 150.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 1988 from 2138, we get 150.
Bring next digit (2) of the dividend behind the 150 and repeat the process: 1502 / 284

Advancing to step 5:
1502 divided by 284 is 5 with a remainder of 82.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 1420 from 1502, we get 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 284

Going ahead to step 6:
821 divided by 284 is 2 with a remainder of 253.
Write down 2 as next digit of the result. 
Result so far: 752.0
Subtract 568 from 821 to get 253.
Include the next digit (5) from the dividend after 253, then repeat: 2535 / 284

Advancing to step 7:
When dividing 2535 by 284, we get 8 with a remainder of 263.
Write down 8 as next digit of the result. 
Result so far: 7528.0
If we take 2272 away from 2535, we end up with 263.
Take the next digit (3) from the dividend and append it to 263, then repeat: 2633 / 284

Going ahead to step 8:
284 can be fit into 2633 9 times, resulting in a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 75289.0
Subtract 2556 from 2633 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
The number 284 fits into 770 2 times, leaving a remainder of 202.
Put 2 as the next digit of the answer. 
Result so far: 75289.2
Subtract 568 from 770 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 10:
284 goes into 2020 7 times with a remainder of 32.
The next digit of our result is 7. 
Result so far: 75289.27
Subtracting 1988 from 2020 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 284, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 75289.271
Subtract 284 from 320 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
284 goes into 360 1 times with a remainder of 76.
The next digit of our result is 1. 
Result so far: 75289.2711
If we subtract 284 from 360, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 75289.2711 with a remainder of 0.00076.
