343886 ÷ 85 
We want to figure out the number of times 343886 can be divided by 85.

On to step 1:
If we divide 3 by 85, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 85

Let's proceed to step 2:
If we divide 34 by 85, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 85

Advancing to step 3:
If we divide 343 by 85, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 340 from 343 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 85

Let's proceed to step 4:
The number 85 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 38, we get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 85

Moving on to step 5:
The number 85 fits into 388 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 404.0
Deduct 340 from 388 and we're left with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 85

Going ahead to step 6:
486 divided by 85 is 5 with a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 4045.0
If we take 425 away from 486, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
If we divide 610 by 85, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 4045.7
If we take 595 away from 610, we end up 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.

Advancing to step 8:
85 goes into 150 1 times with a remainder of 65.
The next digit of our result is 1. 
Result so far: 4045.71
If we take 85 away from 150, we end up 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.

Step 9:
85 goes into 650 7 times with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 4045.717
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
The number 85 fits into 550 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 4045.7176
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.

Advancing to step 11:
When dividing 400 by 85, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 4045.71764
Deduct 340 from 400 and we're left 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.

Moving on to step 12:
85 goes into 600 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4045.717647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
50 divided by 85 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4045.717647
If we take 0 away from 50, we end up 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 14:
500 divided by 85 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 4045.71764705
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.

After the division, we end up with 4045.71764705 and a remainder of 7.5e-08.
