Let's divide 228700 by 21
Our goal is to divide 228700 by 21.

Let's proceed to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Step 2:
22 divided by 21 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 21 from 22 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 21

Advancing to step 3:
The number 21 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 18 to get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 21

On to step 4:
21 can be fit into 187 8 times, resulting in a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 168 from 187 leaves us with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 21

On to step 5:
If we divide 190 by 21, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 1089.0
Deduct 189 from 190 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 21

Advancing to step 6:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10890.0
The remainder is 10 after subtracting 0 from 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 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 10890.4
Subtract 84 from 100 to 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.

Step 8:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 10890.47
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 10890.476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 21 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 10890.4761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 10890.47619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10890.47619
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.

Step 13:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 10890.4761904
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 14:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 10890.47619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 10890.47619047, and the remainder is 1.3e-08.
