We divide 31080814 by 166
Our goal is to divide 31080814 by 166.

Step 1:
166 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 166

Step 2:
31 divided by 166 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 166

Step 3:
166 goes into 310 1 times with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 166 from 310 to get 144.
Grab the next digit (8) from the dividend, add it to 144, then carry on: 1448 / 166

Step 4:
1448 divided by 166 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 1328 from 1448 and we're left with 120.
Fetch the next digit (0) from the dividend, attach it to 120 and continue: 1200 / 166

Advancing to step 5:
166 goes into 1200 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we subtract 1162 from 1200, we get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 166

Moving on to step 6:
When dividing 388 by 166, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 1872.0
Subtracting 332 from 388 leaves us with 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 166

Advancing to step 7:
166 goes into 561 3 times with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 18723.0
Subtracting 498 from 561 leaves us with 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 166

Let's proceed to step 8:
The number 166 fits into 634 3 times, leaving a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 187233.0
Subtract 498 from 634 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 9:
The number 166 fits into 1360 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 187233.8
The remainder is 32 after subtracting 1328 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 166, we get 1 and a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 187233.81
Deduct 166 from 320 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 11:
1540 divided by 166 is 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 187233.819
Subtract 1494 from 1540 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
If we divide 460 by 166, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 187233.8192
Subtract 332 from 460 to 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.

On to step 13:
166 goes into 1280 7 times with a remainder of 118.
The next digit of our result is 7. 
Result so far: 187233.81927
If we take 1162 away from 1280, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 14:
If we divide 1180 by 166, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 187233.819277
Deduct 1162 from 1180 and we're left 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.

After the division, we end up with 187233.819277 and a remainder of 1.8e-06.
