Let's divide 437800 by 85
We're looking to find how many times 85 goes into 437800.

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
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 85

Step 2:
The number 85 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 85

Moving on to step 3:
When dividing 437 by 85, we get 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 425 from 437 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 85

On to step 4:
If we divide 128 by 85, we get 1 and a remainder of 43.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 85 from 128 to get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 85

Advancing to step 5:
When dividing 430 by 85, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
Subtract 425 from 430 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 85

Advancing to step 6:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5150.0
Subtracting 0 from 50 leaves us 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.

Advancing to step 7:
500 divided by 85 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 5150.5
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
85 goes into 750 8 times with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 5150.58
Deduct 680 from 750 and we're left 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.

On to step 9:
85 goes into 700 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 5150.588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 5150.588 with a remainder of 0.002.
