We're dividing 80541891 by 316 
We want to figure out the number of times 80541891 can be divided by 316.

Going ahead to step 1:
8 divided by 316 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 316

Moving on to step 2:
316 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 316

Going ahead to step 3:
The number 316 fits into 805 2 times, leaving a remainder of 173.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 632 from 805, we get 173.
Bring next digit (4) of the dividend behind the 173 and repeat the process: 1734 / 316

Let's proceed to step 4:
When dividing 1734 by 316, we get 5 with a remainder of 154.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 1580 from 1734 leaves us with 154.
Bring next digit (1) of the dividend behind the 154 and repeat the process: 1541 / 316

Let's proceed to step 5:
When dividing 1541 by 316, we get 4 with a remainder of 277.
Use 4 as the next digit of our solution. 
Result so far: 254.0
The remainder is 277 after subtracting 1264 from 1541.
Fetch the next digit (8) from the dividend, attach it to 277 and continue: 2778 / 316

Advancing to step 6:
If we divide 2778 by 316, we get 8 and a remainder of 250.
Write down 8 as next digit of the result. 
Result so far: 2548.0
If we subtract 2528 from 2778, we get 250.
Fetch the next digit (9) from the dividend, attach it to 250 and continue: 2509 / 316

Going ahead to step 7:
The number 316 fits into 2509 7 times, leaving a remainder of 297.
Record the quotient 7 as the next digit in the result. 
Result so far: 25487.0
Subtracting 2212 from 2509 leaves us with 297.
Grab the next digit (1) from the dividend, add it to 297, then carry on: 2971 / 316

Moving on to step 8:
316 goes into 2971 9 times with a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 254879.0
If we take 2844 away from 2971, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
If we divide 1270 by 316, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 254879.4
Deduct 1264 from 1270 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
316 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 254879.4
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
600 divided by 316 is 1 with a remainder of 284.
Use 1 as the next digit of our solution. 
Result so far: 254879.401
Deduct 316 from 600 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 12:
316 goes into 2840 8 times with a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 254879.4018
If we take 2528 away from 2840, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 13:
The number 316 fits into 3120 9 times, leaving a remainder of 276.
Put 9 as the next digit of the answer. 
Result so far: 254879.40189
If we take 2844 away from 3120, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 14:
2760 divided by 316 is 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 254879.401898
Deduct 2528 from 2760 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 15:
316 can be fit into 2320 7 times, resulting in a remainder of 108.
Use 7 as the next digit of our solution. 
Result so far: 254879.4018987
Subtracting 2212 from 2320 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 16:
316 can be fit into 1080 3 times, resulting in a remainder of 132.
The number 3 becomes the next digit in our result. 
Result so far: 254879.40189873
Subtract 948 from 1080 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The quotient of the division is 254879.40189873, and the remainder is 1.32e-07.
