72822998 ÷ 389 
The aim is to understand the frequency of 389 in 72822998.

Step 1:
389 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 389

On to step 2:
When dividing 72 by 389, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 389

On to step 3:
If we divide 728 by 389, we get 1 and a remainder of 339.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 389 from 728 leaves us with 339.
Fetch the next digit (2) from the dividend, attach it to 339 and continue: 3392 / 389

Going ahead to step 4:
If we divide 3392 by 389, we get 8 and a remainder of 280.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 3112 from 3392 to get 280.
Fetch the next digit (2) from the dividend, attach it to 280 and continue: 2802 / 389

Advancing to step 5:
The number 389 fits into 2802 7 times, leaving a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
The remainder is 79 after subtracting 2723 from 2802.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 389

Advancing to step 6:
When dividing 799 by 389, we get 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 1872.0
Subtract 778 from 799 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 389

Moving on to step 7:
The number 389 fits into 219 0 times, leaving a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 18720.0
The remainder is 219 after subtracting 0 from 219.
Grab the next digit (8) from the dividend, add it to 219, then carry on: 2198 / 389

Advancing to step 8:
If we divide 2198 by 389, we get 5 and a remainder of 253.
Write down 5 as next digit of the result. 
Result so far: 187205.0
Deduct 1945 from 2198 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 9:
When dividing 2530 by 389, we get 6 with a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 187205.6
If we take 2334 away from 2530, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
The number 389 fits into 1960 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 187205.65
Deduct 1945 from 1960 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
389 can be fit into 150 0 times, resulting in a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 187205.65
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
1500 divided by 389 is 3 with a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 187205.6503
If we take 1167 away from 1500, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 13:
If we divide 3330 by 389, we get 8 and a remainder of 218.
The number 8 becomes the next digit in our result. 
Result so far: 187205.65038
Deduct 3112 from 3330 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 14:
The number 389 fits into 2180 5 times, leaving a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 187205.650385
If we subtract 1945 from 2180, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 15:
When dividing 2350 by 389, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 187205.6503856
The remainder is 16 after subtracting 2334 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
If we divide 160 by 389, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 187205.6503856
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 187205.6503856 and a remainder of 1.6e-07.
