We divide 91391082 by 166
We want to figure out the number of times 91391082 can be divided by 166.

Let's proceed to step 1:
166 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 166

Moving on to step 2:
166 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 166

On to step 3:
If we divide 913 by 166, we get 5 and a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 830 from 913, we get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 166

Let's proceed to step 4:
166 goes into 839 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 830 away from 839, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 166

Advancing to step 5:
166 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 550.0
Subtract 0 from 91 to get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 166

Step 6:
166 can be fit into 910 5 times, resulting in a remainder of 80.
The next digit of our result is 5. 
Result so far: 5505.0
The remainder is 80 after subtracting 830 from 910.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 166

Advancing to step 7:
166 goes into 808 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 55054.0
Subtract 664 from 808 to get 144.
Fetch the next digit (2) from the dividend, attach it to 144 and continue: 1442 / 166

On to step 8:
The number 166 fits into 1442 8 times, leaving a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 550548.0
Deduct 1328 from 1442 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 9:
166 can be fit into 1140 6 times, resulting in a remainder of 144.
The next digit of our result is 6. 
Result so far: 550548.6
The remainder is 144 after subtracting 996 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 10:
When dividing 1440 by 166, we get 8 with a remainder of 112.
The next digit of our result is 8. 
Result so far: 550548.68
If we take 1328 away from 1440, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
If we divide 1120 by 166, we get 6 and a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 550548.686
If we take 996 away from 1120, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 12:
When dividing 1240 by 166, we get 7 with a remainder of 78.
The next digit of our result is 7. 
Result so far: 550548.6867
If we subtract 1162 from 1240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
When dividing 780 by 166, we get 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 550548.68674
If we subtract 664 from 780, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 14:
If we divide 1160 by 166, we get 6 and a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 550548.686746
Subtract 996 from 1160 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 15:
When dividing 1640 by 166, we get 9 with a remainder of 146.
Use 9 as the next digit of our solution. 
Result so far: 550548.6867469
Deduct 1494 from 1640 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 16:
When dividing 1460 by 166, we get 8 with a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 550548.68674698
Subtracting 1328 from 1460 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 550548.68674698 with a remainder of 1.32e-07.
