We divide 398966 by 85
We want to figure out the number of times 398966 can be divided by 85.

Moving on to step 1:
85 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 85

Going ahead to step 2:
85 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 85

Moving on to step 3:
398 divided by 85 is 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 340 from 398, we get 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 85

Going ahead to step 4:
The number 85 fits into 589 6 times, leaving a remainder of 79.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 510 from 589 leaves us with 79.
Take the next digit (6) from the dividend and append it to 79, then repeat: 796 / 85

Going ahead to step 5:
If we divide 796 by 85, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 469.0
If we subtract 765 from 796, we get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 85

Step 6:
85 goes into 316 3 times with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 4693.0
The remainder is 61 after subtracting 255 from 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
If we divide 610 by 85, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 4693.7
Deduct 595 from 610 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 8:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The next digit of our result is 1. 
Result so far: 4693.71
Subtract 85 from 150 to 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.

Moving on to step 9:
85 can be fit into 650 7 times, resulting in a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 4693.717
If we take 595 away from 650, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
85 can be fit into 550 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 4693.7176
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
The number 85 fits into 400 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4693.71764
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
85 can be fit into 600 7 times, resulting in a remainder of 5.
The next digit of our result is 7. 
Result so far: 4693.717647
Subtracting 595 from 600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
85 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4693.717647
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 4693.71764705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 4693.71764705 with a remainder of 7.5e-08.
