84735044 ÷ 780 
The aim is to understand the frequency of 780 in 84735044.

Advancing to step 1:
When dividing 8 by 780, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 780

Let's proceed to step 2:
780 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 780

On to step 3:
The number 780 fits into 847 1 times, leaving a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 67 after subtracting 780 from 847.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 780

On to step 4:
673 divided by 780 is 0 with a remainder of 673.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 673, we end up with 673.
Bring next digit (5) of the dividend behind the 673 and repeat the process: 6735 / 780

Advancing to step 5:
If we divide 6735 by 780, we get 8 and a remainder of 495.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtract 6240 from 6735 to get 495.
Grab the next digit (0) from the dividend, add it to 495, then carry on: 4950 / 780

Let's proceed to step 6:
When dividing 4950 by 780, we get 6 with a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 1086.0
Subtract 4680 from 4950 to get 270.
Include the next digit (4) from the dividend after 270, then repeat: 2704 / 780

Moving on to step 7:
780 can be fit into 2704 3 times, resulting in a remainder of 364.
The next digit of our result is 3. 
Result so far: 10863.0
If we take 2340 away from 2704, we end up with 364.
Bring next digit (4) of the dividend behind the 364 and repeat the process: 3644 / 780

Advancing to step 8:
If we divide 3644 by 780, we get 4 and a remainder of 524.
The number 4 becomes the next digit in our result. 
Result so far: 108634.0
Deduct 3120 from 3644 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 9:
5240 divided by 780 is 6 with a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 108634.6
If we subtract 4680 from 5240, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 10:
780 can be fit into 5600 7 times, resulting in a remainder of 140.
The number 7 becomes the next digit in our result. 
Result so far: 108634.67
Deduct 5460 from 5600 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 780, we get 1 with a remainder of 620.
The next digit of our result is 1. 
Result so far: 108634.671
If we subtract 780 from 1400, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 12:
When dividing 6200 by 780, we get 7 with a remainder of 740.
Record the quotient 7 as the next digit in the result. 
Result so far: 108634.6717
Subtract 5460 from 6200 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 13:
When dividing 7400 by 780, we get 9 with a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 108634.67179
Subtracting 7020 from 7400 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
780 goes into 3800 4 times with a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 108634.671794
If we subtract 3120 from 3800, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 15:
When dividing 6800 by 780, we get 8 with a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 108634.6717948
Subtracting 6240 from 6800 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 16:
780 can be fit into 5600 7 times, resulting in a remainder of 140.
The next digit of our result is 7. 
Result so far: 108634.67179487
Deduct 5460 from 5600 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 108634.67179487 and a remainder of 1.4e-07.
