We're dividing 21188745 by 826 
Our goal is to divide 21188745 by 826.

Moving on to step 1:
2 divided by 826 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 826

On to step 2:
The number 826 fits into 21 0 times, leaving 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.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 826

Going ahead to step 3:
826 goes into 211 0 times with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Take the next digit (8) from the dividend and append it to 211, then repeat: 2118 / 826

Advancing to step 4:
When dividing 2118 by 826, we get 2 with a remainder of 466.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1652 from 2118 and we're left with 466.
Include the next digit (8) from the dividend after 466, then repeat: 4668 / 826

On to step 5:
If we divide 4668 by 826, we get 5 and a remainder of 538.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 4130 from 4668, we get 538.
Bring next digit (7) of the dividend behind the 538 and repeat the process: 5387 / 826

Going ahead to step 6:
The number 826 fits into 5387 6 times, leaving a remainder of 431.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Subtract 4956 from 5387 to get 431.
Bring next digit (4) of the dividend behind the 431 and repeat the process: 4314 / 826

Let's proceed to step 7:
4314 divided by 826 is 5 with a remainder of 184.
Record the quotient 5 as the next digit in the result. 
Result so far: 2565.0
Deduct 4130 from 4314 and we're left with 184.
Grab the next digit (5) from the dividend, add it to 184, then carry on: 1845 / 826

Advancing to step 8:
The number 826 fits into 1845 2 times, leaving a remainder of 193.
The number 2 becomes the next digit in our result. 
Result so far: 25652.0
The remainder is 193 after subtracting 1652 from 1845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
The number 826 fits into 1930 2 times, leaving a remainder of 278.
Use 2 as the next digit of our solution. 
Result so far: 25652.2
If we take 1652 away from 1930, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 10:
2780 divided by 826 is 3 with a remainder of 302.
Write down 3 as next digit of the result. 
Result so far: 25652.23
If we take 2478 away from 2780, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 11:
When dividing 3020 by 826, we get 3 with a remainder of 542.
Write down 3 as next digit of the result. 
Result so far: 25652.233
The remainder is 542 after subtracting 2478 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The quotient of the division is 25652.233, and the remainder is 0.0542.
