We look at the division of 21428073 by 280 
Let's see how many times 280 fits into 21428073.

On to step 1:
When dividing 2 by 280, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 280

Step 2:
When dividing 21 by 280, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 280

Advancing to step 3:
The number 280 fits into 214 0 times, leaving a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 280

Let's proceed to step 4:
If we divide 2142 by 280, we get 7 and a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 1960 from 2142, we get 182.
Fetch the next digit (8) from the dividend, attach it to 182 and continue: 1828 / 280

Step 5:
When dividing 1828 by 280, we get 6 with a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 1680 away from 1828, we end up with 148.
Bring next digit (0) of the dividend behind the 148 and repeat the process: 1480 / 280

Let's proceed to step 6:
280 can be fit into 1480 5 times, resulting in a remainder of 80.
The next digit of our result is 5. 
Result so far: 765.0
If we subtract 1400 from 1480, we get 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 280

Advancing to step 7:
807 divided by 280 is 2 with a remainder of 247.
Use 2 as the next digit of our solution. 
Result so far: 7652.0
Subtract 560 from 807 to get 247.
Bring next digit (3) of the dividend behind the 247 and repeat the process: 2473 / 280

Advancing to step 8:
When dividing 2473 by 280, we get 8 with a remainder of 233.
Write down 8 as next digit of the result. 
Result so far: 76528.0
Subtracting 2240 from 2473 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 9:
280 goes into 2330 8 times with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 76528.8
The remainder is 90 after subtracting 2240 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
280 can be fit into 900 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 76528.83
If we take 840 away from 900, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 280, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 76528.832
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 76528.8321
If we subtract 280 from 400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 76528.83214
Subtract 1120 from 1200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 76528.832142
The remainder is 240 after subtracting 560 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
280 can be fit into 2400 8 times, resulting in a remainder of 160.
The next digit of our result is 8. 
Result so far: 76528.8321428
Subtracting 2240 from 2400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
If we divide 1600 by 280, we get 5 and a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 76528.83214285
If we subtract 1400 from 1600, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 76528.83214285, and the remainder is 2e-07.
