We're dividing 30719210 by 166 
We want to figure out the number of times 30719210 can be divided by 166.

Moving on to step 1:
166 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 166

Let's proceed to step 2:
166 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 166

Let's proceed to step 3:
166 goes into 307 1 times with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 166 from 307 to get 141.
Bring next digit (1) of the dividend behind the 141 and repeat the process: 1411 / 166

Going ahead to step 4:
If we divide 1411 by 166, we get 8 and a remainder of 83.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 83 after subtracting 1328 from 1411.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 166

Advancing to step 5:
When dividing 839 by 166, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 185.0
If we subtract 830 from 839, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 166

Step 6:
The number 166 fits into 92 0 times, leaving a remainder of 92.
The next digit of our result is 0. 
Result so far: 1850.0
Deduct 0 from 92 and we're left with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 166

Going ahead to step 7:
The number 166 fits into 921 5 times, leaving a remainder of 91.
Put 5 as the next digit of the answer. 
Result so far: 18505.0
If we take 830 away from 921, we end up with 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 166

Let's proceed to step 8:
The number 166 fits into 910 5 times, leaving a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 185055.0
The remainder is 80 after subtracting 830 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
If we divide 800 by 166, we get 4 and a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 185055.4
Deduct 664 from 800 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
1360 divided by 166 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 185055.48
If we take 1328 away from 1360, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
The number 166 fits into 320 1 times, leaving a remainder of 154.
The next digit of our result is 1. 
Result so far: 185055.481
If we take 166 away from 320, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 12:
If we divide 1540 by 166, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 185055.4819
Deduct 1494 from 1540 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
460 divided by 166 is 2 with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 185055.48192
Deduct 332 from 460 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
166 can be fit into 1280 7 times, resulting in a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 185055.481927
Subtracting 1162 from 1280 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 15:
166 goes into 1180 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 185055.4819277
Deduct 1162 from 1180 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 185055.4819277 with a balance of 1.8e-07.
