We look at the division of 99092091 by 388 
Let's see how many times 388 fits into 99092091.

Advancing to step 1:
388 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 388

On to step 2:
99 divided by 388 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 388

Let's proceed to step 3:
When dividing 990 by 388, we get 2 with a remainder of 214.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 776 from 990 and we're left with 214.
Bring next digit (9) of the dividend behind the 214 and repeat the process: 2149 / 388

Going ahead to step 4:
2149 divided by 388 is 5 with a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1940 away from 2149, we end up with 209.
Include the next digit (2) from the dividend after 209, then repeat: 2092 / 388

Going ahead to step 5:
The number 388 fits into 2092 5 times, leaving a remainder of 152.
The next digit of our result is 5. 
Result so far: 255.0
Subtracting 1940 from 2092 leaves us with 152.
Bring next digit (0) of the dividend behind the 152 and repeat the process: 1520 / 388

Let's proceed to step 6:
388 can be fit into 1520 3 times, resulting in a remainder of 356.
Write down 3 as next digit of the result. 
Result so far: 2553.0
Deduct 1164 from 1520 and we're left with 356.
Append the next digit (9) from the dividend to 356 and continue with: 3569 / 388

On to step 7:
388 goes into 3569 9 times with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 25539.0
Deduct 3492 from 3569 and we're left with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 388

Step 8:
388 can be fit into 771 1 times, resulting in a remainder of 383.
Use 1 as the next digit of our solution. 
Result so far: 255391.0
Deduct 388 from 771 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 9:
When dividing 3830 by 388, we get 9 with a remainder of 338.
Put 9 as the next digit of the answer. 
Result so far: 255391.9
Deduct 3492 from 3830 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
If we divide 3380 by 388, we get 8 and a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 255391.98
If we subtract 3104 from 3380, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
When dividing 2760 by 388, we get 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 255391.987
The remainder is 44 after subtracting 2716 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
If we divide 440 by 388, we get 1 and a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 255391.9871
Subtracting 388 from 440 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
When dividing 520 by 388, we get 1 with a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 255391.98711
Subtract 388 from 520 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 255391.98711 with a remaining 0.000132.
