We look at the division of 16827309 by 389 
The aim is to understand the frequency of 389 in 16827309.

Advancing to step 1:
When dividing 1 by 389, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 389

On to step 2:
When dividing 16 by 389, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 389

Moving on to step 3:
When dividing 168 by 389, we get 0 with a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 168 and we're left with 168.
Include the next digit (2) from the dividend after 168, then repeat: 1682 / 389

Moving on to step 4:
1682 divided by 389 is 4 with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1556 from 1682, we get 126.
Append the next digit (7) from the dividend to 126 and continue with: 1267 / 389

Advancing to step 5:
389 goes into 1267 3 times with a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 1167 from 1267, we get 100.
Grab the next digit (3) from the dividend, add it to 100, then carry on: 1003 / 389

On to step 6:
389 can be fit into 1003 2 times, resulting in a remainder of 225.
Write down 2 as next digit of the result. 
Result so far: 432.0
Subtract 778 from 1003 to get 225.
Append the next digit (0) from the dividend to 225 and continue with: 2250 / 389

Advancing to step 7:
When dividing 2250 by 389, we get 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 4325.0
If we take 1945 away from 2250, we end up with 305.
Grab the next digit (9) from the dividend, add it to 305, then carry on: 3059 / 389

Let's proceed to step 8:
3059 divided by 389 is 7 with a remainder of 336.
The next digit of our result is 7. 
Result so far: 43257.0
If we take 2723 away from 3059, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 9:
3360 divided by 389 is 8 with a remainder of 248.
The next digit of our result is 8. 
Result so far: 43257.8
If we subtract 3112 from 3360, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 10:
When dividing 2480 by 389, we get 6 with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 43257.86
If we subtract 2334 from 2480, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
389 can be fit into 1460 3 times, resulting in a remainder of 293.
Use 3 as the next digit of our solution. 
Result so far: 43257.863
Deduct 1167 from 1460 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 12:
2930 divided by 389 is 7 with a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 43257.8637
The remainder is 207 after subtracting 2723 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 13:
When dividing 2070 by 389, we get 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 43257.86375
Subtract 1945 from 2070 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
When dividing 1250 by 389, we get 3 with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 43257.863753
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.

On to step 15:
If we divide 830 by 389, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 43257.8637532
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.

Let's proceed to step 16:
389 can be fit into 520 1 times, resulting in a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 43257.86375321
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.

The quotient of the division is 43257.86375321, and the remainder is 1.31e-07.
