We're dividing 843412 by 68 
We want to divide 843412 by 68.

Moving on to step 1:
The number 68 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 68

Step 2:
When dividing 84 by 68, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 68 away from 84, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 68

Advancing to step 3:
If we divide 163 by 68, we get 2 and a remainder of 27.
The next digit of our result is 2. 
Result so far: 12.0
If we take 136 away from 163, we end up with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 68

Advancing to step 4:
274 divided by 68 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtract 272 from 274 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 68

On to step 5:
The number 68 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 1240.0
If we take 0 away from 21, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 68

On to step 6:
When dividing 212 by 68, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 12403.0
The remainder is 8 after subtracting 204 from 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
68 goes into 80 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 12403.1
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 68, we get 1 and a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 12403.11
If we take 68 away from 120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 12403.11, with a leftover of 0.052.
