We divide 75128840 by 166
We want to figure out the number of times 75128840 can be divided by 166.

On to step 1:
7 divided by 166 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 166

Going ahead to step 2:
166 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 166

Step 3:
166 can be fit into 751 4 times, resulting in a remainder of 87.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 664 from 751 leaves us with 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 166

Advancing to step 4:
When dividing 872 by 166, we get 5 with a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 830 from 872 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 166

Let's proceed to step 5:
428 divided by 166 is 2 with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 452.0
Deduct 332 from 428 and we're left with 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 166

Going ahead to step 6:
The number 166 fits into 968 5 times, leaving a remainder of 138.
The number 5 becomes the next digit in our result. 
Result so far: 4525.0
If we take 830 away from 968, we end up with 138.
Take the next digit (4) from the dividend and append it to 138, then repeat: 1384 / 166

Going ahead to step 7:
166 can be fit into 1384 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 45258.0
Deduct 1328 from 1384 and we're left with 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 166

Going ahead to step 8:
166 goes into 560 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 452583.0
Subtract 498 from 560 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
166 can be fit into 620 3 times, resulting in a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 452583.3
Subtract 498 from 620 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
The number 166 fits into 1220 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 452583.37
Subtracting 1162 from 1220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
166 can be fit into 580 3 times, resulting in a remainder of 82.
The next digit of our result is 3. 
Result so far: 452583.373
If we take 498 away from 580, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
166 goes into 820 4 times with a remainder of 156.
The next digit of our result is 4. 
Result so far: 452583.3734
The remainder is 156 after subtracting 664 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 13:
1560 divided by 166 is 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 452583.37349
Subtracting 1494 from 1560 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
660 divided by 166 is 3 with a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 452583.373493
Subtracting 498 from 660 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 15:
The number 166 fits into 1620 9 times, leaving a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 452583.3734939
The remainder is 126 after subtracting 1494 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 16:
If we divide 1260 by 166, we get 7 and a remainder of 98.
The next digit of our result is 7. 
Result so far: 452583.37349397
If we subtract 1162 from 1260, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final result is 452583.37349397 with a remainder of 9.8e-08.
