We look at the division of 99166638 by 526 
We're looking to find how many times 526 goes into 99166638.

Going ahead to step 1:
If we divide 9 by 526, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 526

Step 2:
526 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 526

Moving on to step 3:
If we divide 991 by 526, we get 1 and a remainder of 465.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 526 from 991 to get 465.
Bring next digit (6) of the dividend behind the 465 and repeat the process: 4656 / 526

Let's proceed to step 4:
526 can be fit into 4656 8 times, resulting in a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 448 after subtracting 4208 from 4656.
Take the next digit (6) from the dividend and append it to 448, then repeat: 4486 / 526

Going ahead to step 5:
526 goes into 4486 8 times with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 188.0
The remainder is 278 after subtracting 4208 from 4486.
Fetch the next digit (6) from the dividend, attach it to 278 and continue: 2786 / 526

Going ahead to step 6:
526 goes into 2786 5 times with a remainder of 156.
The number 5 becomes the next digit in our result. 
Result so far: 1885.0
Deduct 2630 from 2786 and we're left with 156.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 526

Step 7:
526 goes into 1563 2 times with a remainder of 511.
Put 2 as the next digit of the answer. 
Result so far: 18852.0
Deduct 1052 from 1563 and we're left with 511.
Append the next digit (8) from the dividend to 511 and continue with: 5118 / 526

Going ahead to step 8:
When dividing 5118 by 526, we get 9 with a remainder of 384.
Record the quotient 9 as the next digit in the result. 
Result so far: 188529.0
Deduct 4734 from 5118 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 9:
The number 526 fits into 3840 7 times, leaving a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 188529.7
Subtract 3682 from 3840 to 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 10:
The number 526 fits into 1580 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 188529.73
Subtracting 1578 from 1580 leaves us with 2.
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 11:
526 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 188529.73
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
526 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 188529.73
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 188529.73 with a balance of 0.002.
