We look at the division of 63450381 by 784 
The aim is to understand the frequency of 784 in 63450381.

Advancing to step 1:
The number 784 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 784

Moving on to step 2:
784 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 784

Advancing to step 3:
The number 784 fits into 634 0 times, leaving a remainder of 634.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 634 after subtracting 0 from 634.
Fetch the next digit (5) from the dividend, attach it to 634 and continue: 6345 / 784

On to step 4:
When dividing 6345 by 784, we get 8 with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6272 from 6345, we get 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 784

Moving on to step 5:
If we divide 730 by 784, we get 0 and a remainder of 730.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 730 leaves us with 730.
Take the next digit (3) from the dividend and append it to 730, then repeat: 7303 / 784

Advancing to step 6:
784 goes into 7303 9 times with a remainder of 247.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
If we take 7056 away from 7303, we end up with 247.
Include the next digit (8) from the dividend after 247, then repeat: 2478 / 784

Advancing to step 7:
2478 divided by 784 is 3 with a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 8093.0
If we take 2352 away from 2478, we end up with 126.
Grab the next digit (1) from the dividend, add it to 126, then carry on: 1261 / 784

On to step 8:
784 can be fit into 1261 1 times, resulting in a remainder of 477.
The next digit of our result is 1. 
Result so far: 80931.0
If we take 784 away from 1261, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Moving on to step 9:
The number 784 fits into 4770 6 times, leaving a remainder of 66.
The next digit of our result is 6. 
Result so far: 80931.6
Subtract 4704 from 4770 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
When dividing 660 by 784, we get 0 with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 80931.6
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 11:
784 goes into 6600 8 times with a remainder of 328.
The next digit of our result is 8. 
Result so far: 80931.608
Subtracting 6272 from 6600 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
784 can be fit into 3280 4 times, resulting in a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 80931.6084
If we take 3136 away from 3280, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
The number 784 fits into 1440 1 times, leaving a remainder of 656.
Use 1 as the next digit of our solution. 
Result so far: 80931.60841
Subtract 784 from 1440 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 14:
784 goes into 6560 8 times with a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 80931.608418
Deduct 6272 from 6560 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
784 can be fit into 2880 3 times, resulting in a remainder of 528.
Use 3 as the next digit of our solution. 
Result so far: 80931.6084183
If we take 2352 away from 2880, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 16:
When dividing 5280 by 784, we get 6 with a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 80931.60841836
Subtracting 4704 from 5280 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

In conclusion, the division gives 80931.60841836 with a balance of 5.76e-07.
