We're dividing 78845847 by 779 
The aim is to understand the frequency of 779 in 78845847.

Going ahead to step 1:
The number 779 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 779

On to step 2:
779 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 779

Moving on to step 3:
The number 779 fits into 788 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 779 from 788.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 779

Moving on to step 4:
If we divide 94 by 779, we get 0 and a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 94 and we're left with 94.
Grab the next digit (5) from the dividend, add it to 94, then carry on: 945 / 779

Moving on to step 5:
When dividing 945 by 779, we get 1 with a remainder of 166.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 779 from 945 and we're left with 166.
Grab the next digit (8) from the dividend, add it to 166, then carry on: 1668 / 779

Advancing to step 6:
779 goes into 1668 2 times with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 1012.0
Deduct 1558 from 1668 and we're left with 110.
Append the next digit (4) from the dividend to 110 and continue with: 1104 / 779

Step 7:
779 can be fit into 1104 1 times, resulting in a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 10121.0
If we take 779 away from 1104, we end up with 325.
Bring next digit (7) of the dividend behind the 325 and repeat the process: 3257 / 779

Moving on to step 8:
If we divide 3257 by 779, we get 4 and a remainder of 141.
The number 4 becomes the next digit in our result. 
Result so far: 101214.0
If we take 3116 away from 3257, 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.

Moving on to step 9:
If we divide 1410 by 779, we get 1 and a remainder of 631.
The number 1 becomes the next digit in our result. 
Result so far: 101214.1
If we take 779 away from 1410, we end up with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Moving on to step 10:
The number 779 fits into 6310 8 times, leaving a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 101214.18
The remainder is 78 after subtracting 6232 from 6310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
779 can be fit into 780 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 101214.181
If we take 779 away from 780, we end up 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.

Step 12:
10 divided by 779 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 101214.181
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.

Going ahead to step 13:
100 divided by 779 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 101214.181
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 101214.181 with a remaining 0.0001.
