We're dividing 88301991 by 389 
The aim is to understand the frequency of 389 in 88301991.

Step 1:
8 divided by 389 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 389

Step 2:
389 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (3) from the dividend and append it to 88, then repeat: 883 / 389

Let's proceed to step 3:
883 divided by 389 is 2 with a remainder of 105.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 778 from 883 leaves us with 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 389

Step 4:
The number 389 fits into 1050 2 times, leaving a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 778 away from 1050, we end up with 272.
Fetch the next digit (1) from the dividend, attach it to 272 and continue: 2721 / 389

Advancing to step 5:
389 goes into 2721 6 times with a remainder of 387.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
Subtracting 2334 from 2721 leaves us with 387.
Append the next digit (9) from the dividend to 387 and continue with: 3879 / 389

Step 6:
389 goes into 3879 9 times with a remainder of 378.
Write down 9 as next digit of the result. 
Result so far: 2269.0
Subtracting 3501 from 3879 leaves us with 378.
Bring next digit (9) of the dividend behind the 378 and repeat the process: 3789 / 389

Step 7:
3789 divided by 389 is 9 with a remainder of 288.
Record the quotient 9 as the next digit in the result. 
Result so far: 22699.0
The remainder is 288 after subtracting 3501 from 3789.
Take the next digit (1) from the dividend and append it to 288, then repeat: 2881 / 389

Going ahead to step 8:
The number 389 fits into 2881 7 times, leaving a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 226997.0
Subtract 2723 from 2881 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.

Let's proceed to step 9:
When dividing 1580 by 389, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 226997.4
Subtracting 1556 from 1580 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
389 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 226997.4
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
389 goes into 2400 6 times with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 226997.406
Subtract 2334 from 2400 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
The number 389 fits into 660 1 times, leaving a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 226997.4061
Subtract 389 from 660 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 13:
When dividing 2710 by 389, we get 6 with a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 226997.40616
Subtract 2334 from 2710 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 14:
389 goes into 3760 9 times with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 226997.406169
Deduct 3501 from 3760 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 15:
If we divide 2590 by 389, we get 6 and a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 226997.4061696
Subtract 2334 from 2590 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
The number 389 fits into 2560 6 times, leaving a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 226997.40616966
Deduct 2334 from 2560 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Our division results in 226997.40616966 with a remaining 2.26e-07.
