We're dividing 74690911 by 166 
Our goal is to divide 74690911 by 166.

Going ahead to step 1:
7 divided by 166 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 166

Advancing to step 2:
If we divide 74 by 166, we get 0 and a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 166

Let's proceed to step 3:
746 divided by 166 is 4 with a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 82 after subtracting 664 from 746.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 166

Advancing to step 4:
The number 166 fits into 829 4 times, leaving a remainder of 165.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 664 from 829 to get 165.
Append the next digit (0) from the dividend to 165 and continue with: 1650 / 166

Going ahead to step 5:
166 goes into 1650 9 times with a remainder of 156.
The next digit of our result is 9. 
Result so far: 449.0
Subtract 1494 from 1650 to get 156.
Take the next digit (9) from the dividend and append it to 156, then repeat: 1569 / 166

On to step 6:
166 can be fit into 1569 9 times, resulting in a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 4499.0
Subtract 1494 from 1569 to get 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 166

On to step 7:
166 goes into 751 4 times with a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 44994.0
If we subtract 664 from 751, we get 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 166

On to step 8:
If we divide 871 by 166, we get 5 and a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 449945.0
Subtracting 830 from 871 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
166 can be fit into 410 2 times, resulting in a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 449945.2
Subtract 332 from 410 to 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.

Let's proceed to step 10:
780 divided by 166 is 4 with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 449945.24
Subtract 664 from 780 to 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.

Moving on to step 11:
The number 166 fits into 1160 6 times, leaving a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 449945.246
Subtracting 996 from 1160 leaves us with 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 12:
1640 divided by 166 is 9 with a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 449945.2469
Subtracting 1494 from 1640 leaves us 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.

Let's proceed to step 13:
166 can be fit into 1460 8 times, resulting in a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 449945.24698
The remainder is 132 after subtracting 1328 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 14:
1320 divided by 166 is 7 with a remainder of 158.
The next digit of our result is 7. 
Result so far: 449945.246987
If we take 1162 away from 1320, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 15:
1580 divided by 166 is 9 with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 449945.2469879
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.

Going ahead to step 16:
166 can be fit into 860 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 449945.24698795
If we take 830 away from 860, we end up with 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 outcome is 449945.24698795, with a leftover of 3e-08.
