We look at the division of 80970817 by 674 
Our goal is to divide 80970817 by 674.

Step 1:
The number 674 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 674

Moving on to step 2:
674 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 674

Advancing to step 3:
When dividing 809 by 674, we get 1 with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 674 from 809, we get 135.
Take the next digit (7) from the dividend and append it to 135, then repeat: 1357 / 674

Let's proceed to step 4:
When dividing 1357 by 674, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1348 away from 1357, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 674

On to step 5:
90 divided by 674 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 674

Let's proceed to step 6:
674 goes into 908 1 times with a remainder of 234.
Use 1 as the next digit of our solution. 
Result so far: 1201.0
Subtracting 674 from 908 leaves us with 234.
Bring next digit (1) of the dividend behind the 234 and repeat the process: 2341 / 674

Going ahead to step 7:
If we divide 2341 by 674, we get 3 and a remainder of 319.
The next digit of our result is 3. 
Result so far: 12013.0
If we subtract 2022 from 2341, we get 319.
Include the next digit (7) from the dividend after 319, then repeat: 3197 / 674

Step 8:
The number 674 fits into 3197 4 times, leaving a remainder of 501.
Put 4 as the next digit of the answer. 
Result so far: 120134.0
Subtract 2696 from 3197 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 9:
5010 divided by 674 is 7 with a remainder of 292.
Write down 7 as next digit of the result. 
Result so far: 120134.7
The remainder is 292 after subtracting 4718 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 10:
When dividing 2920 by 674, we get 4 with a remainder of 224.
The next digit of our result is 4. 
Result so far: 120134.74
Subtract 2696 from 2920 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 11:
674 goes into 2240 3 times with a remainder of 218.
Write down 3 as next digit of the result. 
Result so far: 120134.743
If we take 2022 away from 2240, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 12:
The number 674 fits into 2180 3 times, leaving a remainder of 158.
Record the quotient 3 as the next digit in the result. 
Result so far: 120134.7433
Subtract 2022 from 2180 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final result is 120134.7433 with a remainder of 0.00158.
