Let's divide 21710492 by 85
We're looking to find how many times 85 goes into 21710492.

Going ahead to step 1:
If we divide 2 by 85, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 85

Advancing to step 2:
85 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 85

Step 3:
217 divided by 85 is 2 with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 170 from 217 and we're left with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 85

On to step 4:
When dividing 471 by 85, we get 5 with a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 425 away from 471, we end up with 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 85

Advancing to step 5:
85 goes into 460 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 255.0
If we take 425 away from 460, we end up with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 85

Going ahead to step 6:
The number 85 fits into 354 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 2554.0
The remainder is 14 after subtracting 340 from 354.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 85

Let's proceed to step 7:
When dividing 149 by 85, we get 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 25541.0
If we take 85 away from 149, we end up with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 85

On to step 8:
85 can be fit into 642 7 times, resulting in a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 255417.0
The remainder is 47 after subtracting 595 from 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
The number 85 fits into 470 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 255417.5
If we subtract 425 from 470, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 85, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 255417.55
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 255417.55, and the remainder is 0.025.
