We look at the division of 21308425 by 828 
Our goal is to divide 21308425 by 828.

Advancing to step 1:
828 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 828

Moving on to step 2:
If we divide 21 by 828, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 828

Advancing to step 3:
When dividing 213 by 828, we get 0 with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Fetch the next digit (0) from the dividend, attach it to 213 and continue: 2130 / 828

Let's proceed to step 4:
When dividing 2130 by 828, we get 2 with a remainder of 474.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1656 away from 2130, we end up with 474.
Bring next digit (8) of the dividend behind the 474 and repeat the process: 4748 / 828

Moving on to step 5:
4748 divided by 828 is 5 with a remainder of 608.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 4140 from 4748 and we're left with 608.
Fetch the next digit (4) from the dividend, attach it to 608 and continue: 6084 / 828

Let's proceed to step 6:
The number 828 fits into 6084 7 times, leaving a remainder of 288.
Write down 7 as next digit of the result. 
Result so far: 257.0
The remainder is 288 after subtracting 5796 from 6084.
Grab the next digit (2) from the dividend, add it to 288, then carry on: 2882 / 828

Advancing to step 7:
The number 828 fits into 2882 3 times, leaving a remainder of 398.
The number 3 becomes the next digit in our result. 
Result so far: 2573.0
The remainder is 398 after subtracting 2484 from 2882.
Take the next digit (5) from the dividend and append it to 398, then repeat: 3985 / 828

Step 8:
If we divide 3985 by 828, we get 4 and a remainder of 673.
Put 4 as the next digit of the answer. 
Result so far: 25734.0
If we take 3312 away from 3985, we end up with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Let's proceed to step 9:
When dividing 6730 by 828, we get 8 with a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 25734.8
Subtracting 6624 from 6730 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 10:
1060 divided by 828 is 1 with a remainder of 232.
The next digit of our result is 1. 
Result so far: 25734.81
The remainder is 232 after subtracting 828 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
The number 828 fits into 2320 2 times, leaving a remainder of 664.
Write down 2 as next digit of the result. 
Result so far: 25734.812
Subtract 1656 from 2320 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Advancing to step 12:
If we divide 6640 by 828, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25734.8128
If we take 6624 away from 6640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
828 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 25734.8128
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
828 can be fit into 1600 1 times, resulting in a remainder of 772.
Use 1 as the next digit of our solution. 
Result so far: 25734.812801
If we subtract 828 from 1600, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

On to step 15:
7720 divided by 828 is 9 with a remainder of 268.
Record the quotient 9 as the next digit in the result. 
Result so far: 25734.8128019
Subtracting 7452 from 7720 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 16:
2680 divided by 828 is 3 with a remainder of 196.
The next digit of our result is 3. 
Result so far: 25734.81280193
If we subtract 2484 from 2680, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final result is 25734.81280193 with a remainder of 1.96e-07.
