We divide 406638 by 85
Our goal is to divide 406638 by 85.

Advancing to step 1:
85 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 85

On to step 2:
The number 85 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 85

Let's proceed to step 3:
The number 85 fits into 406 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 340 from 406, we get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 85

Advancing to step 4:
666 divided by 85 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 595 from 666 and we're left with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 85

Advancing to step 5:
85 can be fit into 713 8 times, resulting in a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 478.0
Subtract 680 from 713 to get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 85

Advancing to step 6:
85 can be fit into 338 3 times, resulting in a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 4783.0
Deduct 255 from 338 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 7:
The number 85 fits into 830 9 times, leaving a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 4783.9
Subtracting 765 from 830 leaves us 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.

On to step 8:
650 divided by 85 is 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 4783.97
The remainder is 55 after subtracting 595 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
The number 85 fits into 550 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4783.976
Subtracting 510 from 550 leaves us 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.

Advancing to step 10:
400 divided by 85 is 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 4783.9764
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.

Let's proceed to step 11:
600 divided by 85 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4783.97647
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.

Going ahead to step 12:
50 divided by 85 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4783.97647
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 85 fits into 500 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4783.9764705
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4783.97647058
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 4783.97647058 with a remainder of 7e-08.
