We look at the division of 80879425 by 345 
We want to divide 80879425 by 345.

Advancing to step 1:
When dividing 8 by 345, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 345

Going ahead to step 2:
When dividing 80 by 345, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 345

Advancing to step 3:
When dividing 808 by 345, we get 2 with a remainder of 118.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 690 from 808 and we're left with 118.
Append the next digit (7) from the dividend to 118 and continue with: 1187 / 345

Step 4:
If we divide 1187 by 345, we get 3 and a remainder of 152.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 1035 from 1187 and we're left with 152.
Append the next digit (9) from the dividend to 152 and continue with: 1529 / 345

Let's proceed to step 5:
When dividing 1529 by 345, we get 4 with a remainder of 149.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we subtract 1380 from 1529, we get 149.
Append the next digit (4) from the dividend to 149 and continue with: 1494 / 345

Going ahead to step 6:
The number 345 fits into 1494 4 times, leaving a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 2344.0
If we subtract 1380 from 1494, we get 114.
Take the next digit (2) from the dividend and append it to 114, then repeat: 1142 / 345

Step 7:
1142 divided by 345 is 3 with a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 23443.0
Deduct 1035 from 1142 and we're left with 107.
Include the next digit (5) from the dividend after 107, then repeat: 1075 / 345

Moving on to step 8:
If we divide 1075 by 345, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 234433.0
If we subtract 1035 from 1075, 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.

Moving on to step 9:
When dividing 400 by 345, we get 1 with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 234433.1
If we subtract 345 from 400, we 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.

Advancing to step 10:
If we divide 550 by 345, we get 1 and a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 234433.11
Subtract 345 from 550 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 234433.11, with a leftover of 0.205.
