Let's divide 21508546 by 835
Let's see how many times 835 fits into 21508546.

Advancing to step 1:
If we divide 2 by 835, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 835

On to step 2:
The number 835 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 835

Advancing to step 3:
835 goes into 215 0 times with a remainder of 215.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 215 and we're left with 215.
Include the next digit (0) from the dividend after 215, then repeat: 2150 / 835

Going ahead to step 4:
835 can be fit into 2150 2 times, resulting in a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1670 from 2150 leaves us with 480.
Fetch the next digit (8) from the dividend, attach it to 480 and continue: 4808 / 835

Step 5:
The number 835 fits into 4808 5 times, leaving a remainder of 633.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 4175 from 4808, we get 633.
Take the next digit (5) from the dividend and append it to 633, then repeat: 6335 / 835

On to step 6:
835 can be fit into 6335 7 times, resulting in a remainder of 490.
Put 7 as the next digit of the answer. 
Result so far: 257.0
If we take 5845 away from 6335, we end up with 490.
Take the next digit (4) from the dividend and append it to 490, then repeat: 4904 / 835

Advancing to step 7:
835 can be fit into 4904 5 times, resulting in a remainder of 729.
Record the quotient 5 as the next digit in the result. 
Result so far: 2575.0
Deduct 4175 from 4904 and we're left with 729.
Append the next digit (6) from the dividend to 729 and continue with: 7296 / 835

Step 8:
When dividing 7296 by 835, we get 8 with a remainder of 616.
Record the quotient 8 as the next digit in the result. 
Result so far: 25758.0
Subtracting 6680 from 7296 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 9:
When dividing 6160 by 835, we get 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 25758.7
If we take 5845 away from 6160, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 10:
The number 835 fits into 3150 3 times, leaving a remainder of 645.
The number 3 becomes the next digit in our result. 
Result so far: 25758.73
The remainder is 645 after subtracting 2505 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 11:
835 goes into 6450 7 times with a remainder of 605.
The next digit of our result is 7. 
Result so far: 25758.737
If we take 5845 away from 6450, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 12:
835 goes into 6050 7 times with a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 25758.7377
The remainder is 205 after subtracting 5845 from 6050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

In conclusion, the division gives 25758.7377 with a balance of 0.00205.
