210412 ÷ 85 
We want to divide 210412 by 85.

Step 1:
2 divided by 85 is 0 with 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 85

Going ahead to step 2:
85 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 85

Advancing to step 3:
If we divide 210 by 85, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 170 from 210 leaves us with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 85

Let's proceed to step 4:
The number 85 fits into 404 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 64 after subtracting 340 from 404.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 85

On to step 5:
If we divide 641 by 85, we get 7 and a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 247.0
Deduct 595 from 641 and we're left with 46.
Append the next digit (2) from the dividend to 46 and continue with: 462 / 85

Step 6:
When dividing 462 by 85, we get 5 with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 2475.0
The remainder is 37 after subtracting 425 from 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
85 can be fit into 370 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 2475.4
The remainder is 30 after subtracting 340 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 85, we get 3 and a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 2475.43
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
85 can be fit into 450 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2475.435
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 2475.4352
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
If we divide 800 by 85, we get 9 and a remainder of 35.
The next digit of our result is 9. 
Result so far: 2475.43529
If we take 765 away from 800, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
85 goes into 350 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2475.435294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 2475.4352941
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
If we divide 150 by 85, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 2475.43529411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 2475.43529411, with a leftover of 6.5e-08.
