Let's divide 89303970 by 166
We want to divide 89303970 by 166.

Step 1:
If we divide 8 by 166, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 166

Moving on to step 2:
166 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Grab the next digit (3) from the dividend, add it to 89, then carry on: 893 / 166

Moving on to step 3:
166 can be fit into 893 5 times, resulting in a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 63 after subtracting 830 from 893.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 166

Moving on to step 4:
The number 166 fits into 630 3 times, leaving a remainder of 132.
The next digit of our result is 3. 
Result so far: 53.0
Subtract 498 from 630 to get 132.
Append the next digit (3) from the dividend to 132 and continue with: 1323 / 166

Advancing to step 5:
When dividing 1323 by 166, we get 7 with a remainder of 161.
Use 7 as the next digit of our solution. 
Result so far: 537.0
Deduct 1162 from 1323 and we're left with 161.
Take the next digit (9) from the dividend and append it to 161, then repeat: 1619 / 166

Advancing to step 6:
166 can be fit into 1619 9 times, resulting in a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 5379.0
Subtracting 1494 from 1619 leaves us with 125.
Grab the next digit (7) from the dividend, add it to 125, then carry on: 1257 / 166

On to step 7:
1257 divided by 166 is 7 with a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 53797.0
Subtracting 1162 from 1257 leaves us with 95.
Append the next digit (0) from the dividend to 95 and continue with: 950 / 166

Moving on to step 8:
If we divide 950 by 166, we get 5 and a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 537975.0
If we subtract 830 from 950, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
The number 166 fits into 1200 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 537975.7
If we take 1162 away from 1200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
166 can be fit into 380 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 537975.72
Subtracting 332 from 380 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
166 goes into 480 2 times with a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 537975.722
Subtracting 332 from 480 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 537975.722 and a remainder of 0.0148.
