We're dividing 75506510 by 166 
Let's see how many times 166 fits into 75506510.

Going ahead to step 1:
The number 166 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 166

Let's proceed to step 2:
75 divided by 166 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 166

On to step 3:
When dividing 755 by 166, we get 4 with a remainder of 91.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 91 after subtracting 664 from 755.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 166

Moving on to step 4:
If we divide 910 by 166, we get 5 and a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 80 after subtracting 830 from 910.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 166

Going ahead to step 5:
When dividing 806 by 166, we get 4 with a remainder of 142.
Put 4 as the next digit of the answer. 
Result so far: 454.0
Subtracting 664 from 806 leaves us with 142.
Grab the next digit (5) from the dividend, add it to 142, then carry on: 1425 / 166

Moving on to step 6:
1425 divided by 166 is 8 with a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 4548.0
The remainder is 97 after subtracting 1328 from 1425.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 166

Advancing to step 7:
If we divide 971 by 166, we get 5 and a remainder of 141.
The next digit of our result is 5. 
Result so far: 45485.0
The remainder is 141 after subtracting 830 from 971.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 166

Let's proceed to step 8:
If we divide 1410 by 166, we get 8 and a remainder of 82.
The next digit of our result is 8. 
Result so far: 454858.0
Subtracting 1328 from 1410 leaves us 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.

On to step 9:
166 goes into 820 4 times with a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 454858.4
Subtracting 664 from 820 leaves us with 156.
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 10:
1560 divided by 166 is 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 454858.49
If we subtract 1494 from 1560, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
166 goes into 660 3 times with a remainder of 162.
Put 3 as the next digit of the answer. 
Result so far: 454858.493
The remainder is 162 after subtracting 498 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 12:
When dividing 1620 by 166, we get 9 with a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 454858.4939
Deduct 1494 from 1620 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 13:
1260 divided by 166 is 7 with a remainder of 98.
The next digit of our result is 7. 
Result so far: 454858.49397
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.

Going ahead to step 14:
The number 166 fits into 980 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 454858.493975
Deduct 830 from 980 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
166 goes into 1500 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 454858.4939759
Subtracting 1494 from 1500 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 16:
The number 166 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 454858.4939759
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 454858.4939759 and a remainder of 6e-08.
