30906343 ÷ 789 
The aim is to understand the frequency of 789 in 30906343.

On to step 1:
If we divide 3 by 789, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 789

Advancing to step 2:
789 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 789

Step 3:
789 can be fit into 309 0 times, resulting in a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Take the next digit (0) from the dividend and append it to 309, then repeat: 3090 / 789

On to step 4:
3090 divided by 789 is 3 with a remainder of 723.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2367 from 3090, we get 723.
Take the next digit (6) from the dividend and append it to 723, then repeat: 7236 / 789

On to step 5:
789 can be fit into 7236 9 times, resulting in a remainder of 135.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 135 after subtracting 7101 from 7236.
Grab the next digit (3) from the dividend, add it to 135, then carry on: 1353 / 789

Advancing to step 6:
The number 789 fits into 1353 1 times, leaving a remainder of 564.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
The remainder is 564 after subtracting 789 from 1353.
Fetch the next digit (4) from the dividend, attach it to 564 and continue: 5644 / 789

Let's proceed to step 7:
When dividing 5644 by 789, we get 7 with a remainder of 121.
The number 7 becomes the next digit in our result. 
Result so far: 3917.0
Subtracting 5523 from 5644 leaves us with 121.
Grab the next digit (3) from the dividend, add it to 121, then carry on: 1213 / 789

On to step 8:
The number 789 fits into 1213 1 times, leaving a remainder of 424.
The next digit of our result is 1. 
Result so far: 39171.0
The remainder is 424 after subtracting 789 from 1213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 9:
789 can be fit into 4240 5 times, resulting in a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 39171.5
The remainder is 295 after subtracting 3945 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 10:
The number 789 fits into 2950 3 times, leaving a remainder of 583.
The number 3 becomes the next digit in our result. 
Result so far: 39171.53
Subtract 2367 from 2950 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

On to step 11:
5830 divided by 789 is 7 with a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 39171.537
Subtract 5523 from 5830 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 12:
789 can be fit into 3070 3 times, resulting in a remainder of 703.
The number 3 becomes the next digit in our result. 
Result so far: 39171.5373
Deduct 2367 from 3070 and we're left with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

On to step 13:
If we divide 7030 by 789, we get 8 and a remainder of 718.
The number 8 becomes the next digit in our result. 
Result so far: 39171.53738
If we take 6312 away from 7030, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Step 14:
789 goes into 7180 9 times with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 39171.537389
Subtracting 7101 from 7180 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 15:
If we divide 790 by 789, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 39171.5373891
Deduct 789 from 790 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 16:
789 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 39171.5373891
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 39171.5373891 and a remainder of 1e-08.
