We're dividing 80811621 by 156 
We want to divide 80811621 by 156.

Advancing to step 1:
8 divided by 156 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 156

Going ahead to step 2:
156 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.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 156

Advancing to step 3:
The number 156 fits into 808 5 times, leaving a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 780 away from 808, we end up with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 156

Going ahead to step 4:
156 can be fit into 281 1 times, resulting in a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 156 from 281, we get 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 156

Let's proceed to step 5:
When dividing 1251 by 156, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 518.0
Deduct 1248 from 1251 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 156

On to step 6:
36 divided by 156 is 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 5180.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 156

Let's proceed to step 7:
362 divided by 156 is 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 51802.0
Deduct 312 from 362 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 156

Going ahead to step 8:
156 can be fit into 501 3 times, resulting in a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 518023.0
Subtract 468 from 501 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
When dividing 330 by 156, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 518023.2
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
156 can be fit into 180 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 518023.21
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 156, we get 1 and a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 518023.211
Subtracting 156 from 240 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 518023.211, and the remainder is 0.0084.
