43812 ÷ 85 
We're looking to find how many times 85 goes into 43812.

Moving on to step 1:
If we divide 4 by 85, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 85

Going ahead to step 2:
85 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 85

Going ahead to step 3:
85 goes into 438 5 times with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 425 from 438 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 85

Moving on to step 4:
If we divide 131 by 85, we get 1 and a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 85 from 131, we get 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 85

Advancing to step 5:
85 can be fit into 462 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 515.0
Deduct 425 from 462 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 6:
If we divide 370 by 85, we get 4 and a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 515.4
If we take 340 away from 370, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 85 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 515.43
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
The number 85 fits into 450 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 515.435
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 85, we get 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 515.4352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 515.43529
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 11:
When dividing 350 by 85, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 515.435294
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 85, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 515.4352941
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
150 divided by 85 is 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 515.43529411
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.

Our division results in 515.43529411 with a remaining 6.5e-08.
