We divide 521398 by 85
We want to figure out the number of times 521398 can be divided by 85.

Let's proceed to step 1:
The number 85 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 85

Moving on to step 2:
When dividing 52 by 85, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 85

Step 3:
85 goes into 521 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 510 from 521 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 85

Step 4:
85 can be fit into 113 1 times, resulting in a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtract 85 from 113 to get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 85

Let's proceed to step 5:
289 divided by 85 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 613.0
Deduct 255 from 289 and we're left with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 85

Going ahead to step 6:
If we divide 348 by 85, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 6134.0
If we subtract 340 from 348, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
85 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6134.0
If we take 0 away from 80, we end up 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.

On to step 8:
800 divided by 85 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 6134.09
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.

Going ahead to step 9:
If we divide 350 by 85, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 6134.094
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 10:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 6134.0941
If we take 85 away from 100, we end up 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.

Going ahead to step 11:
150 divided by 85 is 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 6134.09411
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 6134.09411 with a remaining 6.5e-05.
