Let's divide 21981 by 43
Let's see how many times 43 fits into 21981.

On to step 1:
2 divided by 43 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 43

On to step 2:
When dividing 21 by 43, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 43

Advancing to step 3:
219 divided by 43 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 215 from 219 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 43

Advancing to step 4:
If we divide 48 by 43, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 43 from 48 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 43

On to step 5:
43 can be fit into 51 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 511.0
Subtract 43 from 51 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.

Going ahead to step 6:
43 goes into 80 1 times with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 511.1
The remainder is 37 after subtracting 43 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
When dividing 370 by 43, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 511.18
If we subtract 344 from 370, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
If we divide 260 by 43, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 511.186
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
43 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 511.186
Subtract 0 from 20 to 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.

Moving on to step 10:
If we divide 200 by 43, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 511.18604
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
43 can be fit into 280 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 511.186046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 511.1860465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 511.18604651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 511.18604651, and the remainder is 7e-09.
