We divide 4249558 by 166
We want to divide 4249558 by 166.

Going ahead to step 1:
When dividing 4 by 166, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 166

Step 2:
The number 166 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 166

Going ahead to step 3:
166 can be fit into 424 2 times, resulting in a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 332 from 424 to get 92.
Grab the next digit (9) from the dividend, add it to 92, then carry on: 929 / 166

Step 4:
166 can be fit into 929 5 times, resulting in a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 830 from 929 leaves us with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 166

Moving on to step 5:
166 can be fit into 995 5 times, resulting in a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
If we take 830 away from 995, we end up with 165.
Bring next digit (5) of the dividend behind the 165 and repeat the process: 1655 / 166

Going ahead to step 6:
The number 166 fits into 1655 9 times, leaving a remainder of 161.
The number 9 becomes the next digit in our result. 
Result so far: 2559.0
Subtracting 1494 from 1655 leaves us with 161.
Append the next digit (8) from the dividend to 161 and continue with: 1618 / 166

Let's proceed to step 7:
1618 divided by 166 is 9 with a remainder of 124.
Write down 9 as next digit of the result. 
Result so far: 25599.0
Deduct 1494 from 1618 and we're left 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.

On to step 8:
When dividing 1240 by 166, we get 7 with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 25599.7
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.

Advancing to step 9:
If we divide 780 by 166, we get 4 and a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 25599.74
Subtracting 664 from 780 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 10:
1160 divided by 166 is 6 with a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 25599.746
If we subtract 996 from 1160, we 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.

Moving on to step 11:
166 can be fit into 1640 9 times, resulting in a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 25599.7469
If we subtract 1494 from 1640, we get 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 12:
166 can be fit into 1460 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 25599.74698
If we take 1328 away from 1460, we end up 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.

Step 13:
When dividing 1320 by 166, we get 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 25599.746987
If we subtract 1162 from 1320, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 14:
1580 divided by 166 is 9 with a remainder of 86.
The next digit of our result is 9. 
Result so far: 25599.7469879
If we take 1494 away from 1580, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 15:
166 goes into 860 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 25599.74698795
If we subtract 830 from 860, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 25599.74698795 with a remainder of 3e-08.
