We look at the division of 70542500 by 389 
The aim is to understand the frequency of 389 in 70542500.

Let's proceed to step 1:
When dividing 7 by 389, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 389

Advancing to step 2:
70 divided by 389 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 389

Advancing to step 3:
389 can be fit into 705 1 times, resulting in a remainder of 316.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 316 after subtracting 389 from 705.
Take the next digit (4) from the dividend and append it to 316, then repeat: 3164 / 389

Let's proceed to step 4:
3164 divided by 389 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 3112 from 3164, we get 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 389

On to step 5:
522 divided by 389 is 1 with a remainder of 133.
Use 1 as the next digit of our solution. 
Result so far: 181.0
If we take 389 away from 522, we end up with 133.
Grab the next digit (5) from the dividend, add it to 133, then carry on: 1335 / 389

Let's proceed to step 6:
1335 divided by 389 is 3 with a remainder of 168.
Put 3 as the next digit of the answer. 
Result so far: 1813.0
If we subtract 1167 from 1335, we get 168.
Append the next digit (0) from the dividend to 168 and continue with: 1680 / 389

Let's proceed to step 7:
389 goes into 1680 4 times with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 18134.0
Deduct 1556 from 1680 and we're left with 124.
Include the next digit (0) from the dividend after 124, then repeat: 1240 / 389

Let's proceed to step 8:
When dividing 1240 by 389, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 181343.0
If we subtract 1167 from 1240, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
The number 389 fits into 730 1 times, leaving a remainder of 341.
Write down 1 as next digit of the result. 
Result so far: 181343.1
Subtracting 389 from 730 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 10:
3410 divided by 389 is 8 with a remainder of 298.
The number 8 becomes the next digit in our result. 
Result so far: 181343.18
If we take 3112 away from 3410, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 11:
389 can be fit into 2980 7 times, resulting in a remainder of 257.
Use 7 as the next digit of our solution. 
Result so far: 181343.187
If we take 2723 away from 2980, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 12:
The number 389 fits into 2570 6 times, leaving a remainder of 236.
Put 6 as the next digit of the answer. 
Result so far: 181343.1876
Subtract 2334 from 2570 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 13:
If we divide 2360 by 389, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 181343.18766
Subtract 2334 from 2360 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 181343.18766 with a remainder of 2.6e-05.
