We divide 80971377 by 5
We want to divide 80971377 by 5.

Going ahead to step 1:
If we divide 8 by 5, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 5

Advancing to step 2:
30 divided by 5 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 30 from 30 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 5

Advancing to step 3:
5 goes into 9 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 161.0
The remainder is 4 after subtracting 5 from 9.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 5

Advancing to step 4:
5 goes into 47 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1619.0
If we take 45 away from 47, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 5

Moving on to step 5:
The number 5 fits into 21 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 16194.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 5

Let's proceed to step 6:
5 goes into 13 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 161942.0
If we take 10 away from 13, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 5

Let's proceed to step 7:
When dividing 37 by 5, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1619427.0
Subtracting 35 from 37 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 5

Going ahead to step 8:
5 can be fit into 27 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 16194275.0
Subtract 25 from 27 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
5 goes into 20 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 16194275.4
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 16194275.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16194275.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 16194275.4 and a remainder of 0.0.
