80853748 ÷ 166 
Our goal is to divide 80853748 by 166.

On to step 1:
When dividing 8 by 166, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 166

Going ahead to step 2:
80 divided by 166 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 166

Going ahead to step 3:
166 can be fit into 808 4 times, resulting in a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 664 from 808 to get 144.
Include the next digit (5) from the dividend after 144, then repeat: 1445 / 166

Going ahead to step 4:
If we divide 1445 by 166, we get 8 and a remainder of 117.
Write down 8 as next digit of the result. 
Result so far: 48.0
The remainder is 117 after subtracting 1328 from 1445.
Bring next digit (3) of the dividend behind the 117 and repeat the process: 1173 / 166

Advancing to step 5:
166 can be fit into 1173 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 487.0
Subtract 1162 from 1173 to get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 166

Going ahead to step 6:
166 goes into 117 0 times with a remainder of 117.
Record the quotient 0 as the next digit in the result. 
Result so far: 4870.0
Deduct 0 from 117 and we're left with 117.
Include the next digit (4) from the dividend after 117, then repeat: 1174 / 166

Moving on to step 7:
1174 divided by 166 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 48707.0
Deduct 1162 from 1174 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 166

Going ahead to step 8:
If we divide 128 by 166, we get 0 and a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 487070.0
If we subtract 0 from 128, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 9:
1280 divided by 166 is 7 with a remainder of 118.
The number 7 becomes the next digit in our result. 
Result so far: 487070.7
Subtract 1162 from 1280 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
When dividing 1180 by 166, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 487070.77
Subtracting 1162 from 1180 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.

The quotient of the division is 487070.77, and the remainder is 0.018.
