We're dividing 670340 by 85 
We want to divide 670340 by 85.

Going ahead to step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 85

On to step 2:
When dividing 67 by 85, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 85

Going ahead to step 3:
85 can be fit into 670 7 times, resulting in a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 595 from 670 leaves us with 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 85

Moving on to step 4:
When dividing 753 by 85, we get 8 with a remainder of 73.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 73 after subtracting 680 from 753.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 85

Moving on to step 5:
85 can be fit into 734 8 times, resulting in a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 788.0
Subtracting 680 from 734 leaves us with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 85

Step 6:
85 can be fit into 540 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 7886.0
Deduct 510 from 540 and we're left 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.

Advancing to step 7:
300 divided by 85 is 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 7886.3
If we subtract 255 from 300, we 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.

Advancing to step 8:
85 goes into 450 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7886.35
Subtract 425 from 450 to 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.

Step 9:
250 divided by 85 is 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 7886.352
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
85 can be fit into 800 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 7886.3529
Deduct 765 from 800 and we're left 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.

Advancing to step 11:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 7886.35294
Subtracting 340 from 350 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 7886.352941
Deduct 85 from 100 and we're left 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 13:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 7886.3529411
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.

After the division, we end up with 7886.3529411 and a remainder of 6.5e-07.
