We're dividing 21187402 by 252 
Our goal is to divide 21187402 by 252.

Let's proceed to step 1:
The number 252 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 252

Moving on to step 2:
252 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 252

On to step 3:
If we divide 211 by 252, we get 0 and a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Grab the next digit (8) from the dividend, add it to 211, then carry on: 2118 / 252

On to step 4:
2118 divided by 252 is 8 with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 2016 from 2118 to get 102.
Append the next digit (7) from the dividend to 102 and continue with: 1027 / 252

Going ahead to step 5:
252 goes into 1027 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 19 after subtracting 1008 from 1027.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 252

Moving on to step 6:
252 can be fit into 194 0 times, resulting in a remainder of 194.
The number 0 becomes the next digit in our result. 
Result so far: 840.0
Subtract 0 from 194 to get 194.
Take the next digit (0) from the dividend and append it to 194, then repeat: 1940 / 252

Let's proceed to step 7:
If we divide 1940 by 252, we get 7 and a remainder of 176.
The number 7 becomes the next digit in our result. 
Result so far: 8407.0
The remainder is 176 after subtracting 1764 from 1940.
Grab the next digit (2) from the dividend, add it to 176, then carry on: 1762 / 252

Going ahead to step 8:
252 can be fit into 1762 6 times, resulting in a remainder of 250.
Put 6 as the next digit of the answer. 
Result so far: 84076.0
If we take 1512 away from 1762, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 9:
2500 divided by 252 is 9 with a remainder of 232.
The number 9 becomes the next digit in our result. 
Result so far: 84076.9
The remainder is 232 after subtracting 2268 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 10:
252 can be fit into 2320 9 times, resulting in a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 84076.99
Subtract 2268 from 2320 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 84076.99, and the remainder is 0.052.
