Let's divide 17638370 by 166
We want to figure out the number of times 17638370 can be divided by 166.

Moving on to step 1:
1 divided by 166 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 166

Step 2:
When dividing 17 by 166, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 166

Advancing to step 3:
If we divide 176 by 166, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 166 from 176 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 166

Step 4:
103 divided by 166 is 0 with a remainder of 103.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 103 to get 103.
Include the next digit (8) from the dividend after 103, then repeat: 1038 / 166

Step 5:
166 goes into 1038 6 times with a remainder of 42.
The next digit of our result is 6. 
Result so far: 106.0
Deduct 996 from 1038 and we're left with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 166

Step 6:
When dividing 423 by 166, we get 2 with a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 1062.0
Subtract 332 from 423 to get 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 166

Advancing to step 7:
If we divide 917 by 166, we get 5 and a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 10625.0
If we take 830 away from 917, we end up with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 166

Step 8:
If we divide 870 by 166, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 106255.0
Subtract 830 from 870 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
166 can be fit into 400 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 106255.2
The remainder is 68 after subtracting 332 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 166 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 106255.24
If we take 664 away from 680, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 166, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 106255.24
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
1600 divided by 166 is 9 with a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 106255.2409
Subtract 1494 from 1600 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
1060 divided by 166 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 106255.24096
If we take 996 away from 1060, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
640 divided by 166 is 3 with a remainder of 142.
Use 3 as the next digit of our solution. 
Result so far: 106255.240963
If we subtract 498 from 640, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 15:
The number 166 fits into 1420 8 times, leaving a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 106255.2409638
If we take 1328 away from 1420, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 16:
166 can be fit into 920 5 times, resulting in a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 106255.24096385
The remainder is 90 after subtracting 830 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 106255.24096385 with a remainder of 9e-08.
