80478603 divided by 346 
We want to figure out the number of times 80478603 can be divided by 346.

Going ahead to step 1:
The number 346 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 346

Advancing to step 2:
346 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 346

Step 3:
If we divide 804 by 346, we get 2 and a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 112 after subtracting 692 from 804.
Append the next digit (7) from the dividend to 112 and continue with: 1127 / 346

On to step 4:
The number 346 fits into 1127 3 times, leaving a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 1038 from 1127 and we're left with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 346

Let's proceed to step 5:
346 can be fit into 898 2 times, resulting in a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Subtract 692 from 898 to get 206.
Grab the next digit (6) from the dividend, add it to 206, then carry on: 2066 / 346

Step 6:
2066 divided by 346 is 5 with a remainder of 336.
Put 5 as the next digit of the answer. 
Result so far: 2325.0
Deduct 1730 from 2066 and we're left with 336.
Fetch the next digit (0) from the dividend, attach it to 336 and continue: 3360 / 346

Advancing to step 7:
If we divide 3360 by 346, we get 9 and a remainder of 246.
Put 9 as the next digit of the answer. 
Result so far: 23259.0
Subtract 3114 from 3360 to get 246.
Fetch the next digit (3) from the dividend, attach it to 246 and continue: 2463 / 346

Moving on to step 8:
When dividing 2463 by 346, we get 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 232597.0
If we take 2422 away from 2463, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
410 divided by 346 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 232597.1
The remainder is 64 after subtracting 346 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
When dividing 640 by 346, we get 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 232597.11
If we subtract 346 from 640, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

After the division, we end up with 232597.11 and a remainder of 0.294.
