21036114 ÷ 43 
We want to figure out the number of times 21036114 can be divided by 43.

Advancing to step 1:
43 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 43

Moving on to step 2:
If we divide 21 by 43, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 43

Going ahead to step 3:
If we divide 210 by 43, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 172 from 210 to get 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 43

Advancing to step 4:
When dividing 383 by 43, we get 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 344 from 383 to get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 43

Going ahead to step 5:
43 can be fit into 396 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 489.0
If we take 387 away from 396, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 43

Advancing to step 6:
The number 43 fits into 91 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 4892.0
Subtract 86 from 91 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 43

Let's proceed to step 7:
The number 43 fits into 51 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 48921.0
If we subtract 43 from 51, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 43

Let's proceed to step 8:
When dividing 84 by 43, we get 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 489211.0
Subtracting 43 from 84 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
43 can be fit into 410 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 489211.9
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
43 can be fit into 230 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 489211.95
If we take 215 away from 230, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
43 goes into 150 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 489211.953
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 489211.9534
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 43, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 489211.95348
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
The number 43 fits into 360 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 489211.953488
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 489211.953488, with a leftover of 1.6e-06.
