80430677 divided by 607 
Our goal is to divide 80430677 by 607.

Let's proceed to step 1:
If we divide 8 by 607, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 607

Going ahead to step 2:
607 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 607

Going ahead to step 3:
804 divided by 607 is 1 with a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 607 from 804, we get 197.
Include the next digit (3) from the dividend after 197, then repeat: 1973 / 607

Moving on to step 4:
1973 divided by 607 is 3 with a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1821 from 1973 to get 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 607

Going ahead to step 5:
607 goes into 1520 2 times with a remainder of 306.
The next digit of our result is 2. 
Result so far: 132.0
Subtracting 1214 from 1520 leaves us with 306.
Append the next digit (6) from the dividend to 306 and continue with: 3066 / 607

Let's proceed to step 6:
607 goes into 3066 5 times with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 1325.0
Deduct 3035 from 3066 and we're left with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 607

Going ahead to step 7:
When dividing 317 by 607, we get 0 with a remainder of 317.
Write down 0 as next digit of the result. 
Result so far: 13250.0
The remainder is 317 after subtracting 0 from 317.
Include the next digit (7) from the dividend after 317, then repeat: 3177 / 607

Step 8:
607 can be fit into 3177 5 times, resulting in a remainder of 142.
Write down 5 as next digit of the result. 
Result so far: 132505.0
If we take 3035 away from 3177, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
If we divide 1420 by 607, we get 2 and a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 132505.2
Subtracting 1214 from 1420 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 10:
The number 607 fits into 2060 3 times, leaving a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 132505.23
Deduct 1821 from 2060 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 11:
The number 607 fits into 2390 3 times, leaving a remainder of 569.
The number 3 becomes the next digit in our result. 
Result so far: 132505.233
If we subtract 1821 from 2390, we get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

The final outcome is 132505.233, with a leftover of 0.0569.
