78341964 ÷ 783 
The aim is to understand the frequency of 783 in 78341964.

Let's proceed to step 1:
783 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 783

Going ahead to step 2:
783 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 783

Step 3:
783 divided by 783 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 783 from 783 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 783

Moving on to step 4:
783 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 783

Going ahead to step 5:
If we divide 41 by 783, we get 0 and a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 41 and we're left with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 783

Moving on to step 6:
The number 783 fits into 419 0 times, leaving a remainder of 419.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
Deduct 0 from 419 and we're left with 419.
Fetch the next digit (6) from the dividend, attach it to 419 and continue: 4196 / 783

Going ahead to step 7:
If we divide 4196 by 783, we get 5 and a remainder of 281.
The next digit of our result is 5. 
Result so far: 10005.0
Deduct 3915 from 4196 and we're left with 281.
Include the next digit (4) from the dividend after 281, then repeat: 2814 / 783

Let's proceed to step 8:
2814 divided by 783 is 3 with a remainder of 465.
Write down 3 as next digit of the result. 
Result so far: 100053.0
The remainder is 465 after subtracting 2349 from 2814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 9:
If we divide 4650 by 783, we get 5 and a remainder of 735.
Use 5 as the next digit of our solution. 
Result so far: 100053.5
Subtracting 3915 from 4650 leaves us with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 10:
When dividing 7350 by 783, we get 9 with a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 100053.59
Subtract 7047 from 7350 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 11:
3030 divided by 783 is 3 with a remainder of 681.
The number 3 becomes the next digit in our result. 
Result so far: 100053.593
The remainder is 681 after subtracting 2349 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Moving on to step 12:
If we divide 6810 by 783, we get 8 and a remainder of 546.
Use 8 as the next digit of our solution. 
Result so far: 100053.5938
If we subtract 6264 from 6810, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 13:
5460 divided by 783 is 6 with a remainder of 762.
Write down 6 as next digit of the result. 
Result so far: 100053.59386
Deduct 4698 from 5460 and we're left with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Step 14:
783 goes into 7620 9 times with a remainder of 573.
The next digit of our result is 9. 
Result so far: 100053.593869
If we take 7047 away from 7620, we end up with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

On to step 15:
When dividing 5730 by 783, we get 7 with a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 100053.5938697
If we subtract 5481 from 5730, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 16:
If we divide 2490 by 783, we get 3 and a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 100053.59386973
If we take 2349 away from 2490, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Our division results in 100053.59386973 with a remaining 1.41e-07.
