99620304 divided by 166 
We want to divide 99620304 by 166.

Let's proceed to step 1:
When dividing 9 by 166, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 166

On to step 2:
99 divided by 166 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (6) from the dividend to 99 and continue with: 996 / 166

On to step 3:
166 can be fit into 996 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 996 away from 996, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 166

Advancing to step 4:
166 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 166

On to step 5:
166 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 600.0
Subtract 0 from 20 to get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 166

Going ahead to step 6:
203 divided by 166 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 6001.0
If we take 166 away from 203, we end up with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 166

On to step 7:
166 goes into 370 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 60012.0
Subtracting 332 from 370 leaves us with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 166

Advancing to step 8:
The number 166 fits into 384 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 600122.0
Subtract 332 from 384 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
If we divide 520 by 166, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 600122.3
If we subtract 498 from 520, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
166 can be fit into 220 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 600122.31
Subtracting 166 from 220 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
If we divide 540 by 166, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 600122.313
Deduct 498 from 540 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
The number 166 fits into 420 2 times, leaving a remainder of 88.
The next digit of our result is 2. 
Result so far: 600122.3132
If we subtract 332 from 420, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
166 goes into 880 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 600122.31325
Deduct 830 from 880 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
The number 166 fits into 500 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 600122.313253
The remainder is 2 after subtracting 498 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
166 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 600122.313253
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
200 divided by 166 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 600122.31325301
If we take 166 away from 200, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 600122.31325301 with a balance of 3.4e-08.
