We look at the division of 27975920 by 389 
The aim is to understand the frequency of 389 in 27975920.

Advancing to step 1:
389 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 389

Step 2:
389 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 389

Going ahead to step 3:
If we divide 279 by 389, we get 0 and a remainder of 279.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 279 and we're left with 279.
Append the next digit (7) from the dividend to 279 and continue with: 2797 / 389

On to step 4:
If we divide 2797 by 389, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2723 from 2797 to get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 389

On to step 5:
If we divide 745 by 389, we get 1 and a remainder of 356.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtracting 389 from 745 leaves us with 356.
Include the next digit (9) from the dividend after 356, then repeat: 3569 / 389

Advancing to step 6:
389 goes into 3569 9 times with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 719.0
Subtracting 3501 from 3569 leaves us with 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 389

Moving on to step 7:
When dividing 682 by 389, we get 1 with a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 7191.0
If we subtract 389 from 682, we get 293.
Bring next digit (0) of the dividend behind the 293 and repeat the process: 2930 / 389

Let's proceed to step 8:
The number 389 fits into 2930 7 times, leaving a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 71917.0
Subtract 2723 from 2930 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
389 goes into 2070 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 71917.5
The remainder is 125 after subtracting 1945 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
The number 389 fits into 1250 3 times, leaving a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 71917.53
If we subtract 1167 from 1250, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 11:
When dividing 830 by 389, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 71917.532
If we take 778 away from 830, we end up 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.

Advancing to step 12:
The number 389 fits into 520 1 times, leaving a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 71917.5321
Deduct 389 from 520 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 13:
The number 389 fits into 1310 3 times, leaving a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 71917.53213
Subtracting 1167 from 1310 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 14:
If we divide 1430 by 389, we get 3 and a remainder of 263.
The next digit of our result is 3. 
Result so far: 71917.532133
Deduct 1167 from 1430 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The quotient of the division is 71917.532133, and the remainder is 2.63e-05.
