398137 ÷ 85 
We want to divide 398137 by 85.

Going ahead to step 1:
85 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 85

On to step 2:
85 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 85

Advancing to step 3:
The number 85 fits into 398 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 340 from 398 to get 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 85

Let's proceed to step 4:
If we divide 581 by 85, we get 6 and a remainder of 71.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 71 after subtracting 510 from 581.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 85

Moving on to step 5:
713 divided by 85 is 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 468.0
The remainder is 33 after subtracting 680 from 713.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 85

Advancing to step 6:
337 divided by 85 is 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 4683.0
Subtracting 255 from 337 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 7:
820 divided by 85 is 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 4683.9
Deduct 765 from 820 and we're left 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 8:
The number 85 fits into 550 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 4683.96
If we take 510 away from 550, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 85, we get 4 and a remainder of 60.
The next digit of our result is 4. 
Result so far: 4683.964
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
85 goes into 600 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 4683.9647
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.

Advancing to step 11:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4683.9647
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 85, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 4683.964705
If we subtract 425 from 500, we 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.

Let's proceed to step 13:
If we divide 750 by 85, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 4683.9647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 4683.96470588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 4683.96470588, and the remainder is 2e-08.
