We're dividing 532186 by 21 
Our goal is to divide 532186 by 21.

Moving on to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Let's proceed to step 2:
21 can be fit into 53 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 11 after subtracting 42 from 53.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 21

Advancing to step 3:
112 divided by 21 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 105 away from 112, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 21

Going ahead to step 4:
If we divide 71 by 21, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
Deduct 63 from 71 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Step 5:
When dividing 88 by 21, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 2534.0
Subtract 84 from 88 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 21

Step 6:
If we divide 46 by 21, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 25342.0
Subtract 42 from 46 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 25342.1
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.

Let's proceed to step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 25342.19
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.

Going ahead to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 25342.19
If we subtract 0 from 10, we 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.

Advancing to step 10:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 25342.1904
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.

Moving on to step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 25342.19047
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 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 25342.190476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 25342.1904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 25342.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 25342.19047619, and the remainder is 1e-09.
