We're dividing 81157335 by 166 
Let's see how many times 166 fits into 81157335.

Let's proceed to step 1:
166 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 166

Advancing to step 2:
When dividing 81 by 166, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 166

Advancing to step 3:
When dividing 811 by 166, we get 4 with a remainder of 147.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 664 from 811 to get 147.
Grab the next digit (5) from the dividend, add it to 147, then carry on: 1475 / 166

Let's proceed to step 4:
1475 divided by 166 is 8 with a remainder of 147.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 1328 from 1475 to get 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 166

Moving on to step 5:
If we divide 1477 by 166, we get 8 and a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 488.0
If we subtract 1328 from 1477, we get 149.
Include the next digit (3) from the dividend after 149, then repeat: 1493 / 166

Going ahead to step 6:
1493 divided by 166 is 8 with a remainder of 165.
The next digit of our result is 8. 
Result so far: 4888.0
The remainder is 165 after subtracting 1328 from 1493.
Grab the next digit (3) from the dividend, add it to 165, then carry on: 1653 / 166

Going ahead to step 7:
When dividing 1653 by 166, we get 9 with a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 48889.0
Subtracting 1494 from 1653 leaves us with 159.
Take the next digit (5) from the dividend and append it to 159, then repeat: 1595 / 166

Moving on to step 8:
When dividing 1595 by 166, we get 9 with a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 488899.0
Subtract 1494 from 1595 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
When dividing 1010 by 166, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 488899.6
Deduct 996 from 1010 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
166 goes into 140 0 times with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 488899.6
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
The number 166 fits into 1400 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 488899.608
If we subtract 1328 from 1400, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
166 goes into 720 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 488899.6084
The remainder is 56 after subtracting 664 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
When dividing 560 by 166, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 488899.60843
The remainder is 62 after subtracting 498 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
166 goes into 620 3 times with a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 488899.608433
If we take 498 away from 620, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

In conclusion, the division gives 488899.608433 with a balance of 1.22e-05.
