We look at the division of 77490923 by 782 
The aim is to understand the frequency of 782 in 77490923.

Let's proceed to step 1:
782 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 782

Advancing to step 2:
When dividing 77 by 782, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 782

Going ahead to step 3:
If we divide 774 by 782, we get 0 and a remainder of 774.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 774, we end up with 774.
Grab the next digit (9) from the dividend, add it to 774, then carry on: 7749 / 782

Going ahead to step 4:
The number 782 fits into 7749 9 times, leaving a remainder of 711.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7038 from 7749, we get 711.
Append the next digit (0) from the dividend to 711 and continue with: 7110 / 782

Going ahead to step 5:
782 goes into 7110 9 times with a remainder of 72.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 7038 from 7110 and we're left with 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 782

Step 6:
If we divide 729 by 782, we get 0 and a remainder of 729.
Write down 0 as next digit of the result. 
Result so far: 990.0
If we take 0 away from 729, we end up with 729.
Include the next digit (2) from the dividend after 729, then repeat: 7292 / 782

Let's proceed to step 7:
If we divide 7292 by 782, we get 9 and a remainder of 254.
Use 9 as the next digit of our solution. 
Result so far: 9909.0
Deduct 7038 from 7292 and we're left with 254.
Bring next digit (3) of the dividend behind the 254 and repeat the process: 2543 / 782

Let's proceed to step 8:
If we divide 2543 by 782, we get 3 and a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 99093.0
Deduct 2346 from 2543 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 9:
782 goes into 1970 2 times with a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 99093.2
Deduct 1564 from 1970 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 10:
782 can be fit into 4060 5 times, resulting in a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 99093.25
If we take 3910 away from 4060, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
782 goes into 1500 1 times with a remainder of 718.
Write down 1 as next digit of the result. 
Result so far: 99093.251
Deduct 782 from 1500 and we're left 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.

On to step 12:
If we divide 7180 by 782, we get 9 and a remainder of 142.
Write down 9 as next digit of the result. 
Result so far: 99093.2519
If we subtract 7038 from 7180, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 13:
If we divide 1420 by 782, we get 1 and a remainder of 638.
The next digit of our result is 1. 
Result so far: 99093.25191
Deduct 782 from 1420 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 14:
782 goes into 6380 8 times with a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 99093.251918
Subtracting 6256 from 6380 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 15:
When dividing 1240 by 782, we get 1 with a remainder of 458.
Put 1 as the next digit of the answer. 
Result so far: 99093.2519181
If we subtract 782 from 1240, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 16:
782 can be fit into 4580 5 times, resulting in a remainder of 670.
The next digit of our result is 5. 
Result so far: 99093.25191815
Subtract 3910 from 4580 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Our division results in 99093.25191815 with a remaining 6.7e-07.
