We look at the division of 21485623 by 829 
We want to figure out the number of times 21485623 can be divided by 829.

Let's proceed to step 1:
2 divided by 829 is 0 with a remainder of 2.
The next digit of our result is 0. 
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 / 829

Advancing to step 2:
829 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 829

Moving on to step 3:
214 divided by 829 is 0 with a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 214, we end up with 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 829

On to step 4:
2148 divided by 829 is 2 with a remainder of 490.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1658 from 2148 leaves us with 490.
Bring next digit (5) of the dividend behind the 490 and repeat the process: 4905 / 829

Advancing to step 5:
4905 divided by 829 is 5 with a remainder of 760.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 4145 from 4905 leaves us with 760.
Append the next digit (6) from the dividend to 760 and continue with: 7606 / 829

Step 6:
7606 divided by 829 is 9 with a remainder of 145.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
Deduct 7461 from 7606 and we're left with 145.
Take the next digit (2) from the dividend and append it to 145, then repeat: 1452 / 829

Step 7:
829 can be fit into 1452 1 times, resulting in a remainder of 623.
The number 1 becomes the next digit in our result. 
Result so far: 2591.0
The remainder is 623 after subtracting 829 from 1452.
Take the next digit (3) from the dividend and append it to 623, then repeat: 6233 / 829

Advancing to step 8:
The number 829 fits into 6233 7 times, leaving a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 25917.0
If we subtract 5803 from 6233, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 9:
829 goes into 4300 5 times with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 25917.5
Deduct 4145 from 4300 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 10:
When dividing 1550 by 829, we get 1 with a remainder of 721.
The number 1 becomes the next digit in our result. 
Result so far: 25917.51
Subtract 829 from 1550 to get 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Moving on to step 11:
829 can be fit into 7210 8 times, resulting in a remainder of 578.
Record the quotient 8 as the next digit in the result. 
Result so far: 25917.518
If we subtract 6632 from 7210, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 12:
When dividing 5780 by 829, we get 6 with a remainder of 806.
Use 6 as the next digit of our solution. 
Result so far: 25917.5186
Subtracting 4974 from 5780 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Advancing to step 13:
829 goes into 8060 9 times with a remainder of 599.
Put 9 as the next digit of the answer. 
Result so far: 25917.51869
Deduct 7461 from 8060 and we're left with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 14:
When dividing 5990 by 829, we get 7 with a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 25917.518697
Subtracting 5803 from 5990 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 15:
829 goes into 1870 2 times with a remainder of 212.
The next digit of our result is 2. 
Result so far: 25917.5186972
The remainder is 212 after subtracting 1658 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 16:
If we divide 2120 by 829, we get 2 and a remainder of 462.
Put 2 as the next digit of the answer. 
Result so far: 25917.51869722
The remainder is 462 after subtracting 1658 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Our division results in 25917.51869722 with a remaining 4.62e-07.
