We look at the division of 77481526 by 847 
The aim is to understand the frequency of 847 in 77481526.

Advancing to step 1:
847 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 847

Step 2:
When dividing 77 by 847, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 847

Moving on to step 3:
When dividing 774 by 847, we get 0 with a remainder of 774.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 774 and we're left with 774.
Fetch the next digit (8) from the dividend, attach it to 774 and continue: 7748 / 847

On to step 4:
847 can be fit into 7748 9 times, resulting in a remainder of 125.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 7623 from 7748 to get 125.
Grab the next digit (1) from the dividend, add it to 125, then carry on: 1251 / 847

Let's proceed to step 5:
The number 847 fits into 1251 1 times, leaving a remainder of 404.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtract 847 from 1251 to get 404.
Take the next digit (5) from the dividend and append it to 404, then repeat: 4045 / 847

Moving on to step 6:
4045 divided by 847 is 4 with a remainder of 657.
The number 4 becomes the next digit in our result. 
Result so far: 914.0
If we subtract 3388 from 4045, we get 657.
Include the next digit (2) from the dividend after 657, then repeat: 6572 / 847

Step 7:
847 goes into 6572 7 times with a remainder of 643.
Put 7 as the next digit of the answer. 
Result so far: 9147.0
If we subtract 5929 from 6572, we get 643.
Bring next digit (6) of the dividend behind the 643 and repeat the process: 6436 / 847

On to step 8:
When dividing 6436 by 847, we get 7 with a remainder of 507.
Record the quotient 7 as the next digit in the result. 
Result so far: 91477.0
If we take 5929 away from 6436, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 9:
When dividing 5070 by 847, we get 5 with a remainder of 835.
Use 5 as the next digit of our solution. 
Result so far: 91477.5
The remainder is 835 after subtracting 4235 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

On to step 10:
847 can be fit into 8350 9 times, resulting in a remainder of 727.
Write down 9 as next digit of the result. 
Result so far: 91477.59
Subtracting 7623 from 8350 leaves us with 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Advancing to step 11:
If we divide 7270 by 847, we get 8 and a remainder of 494.
Record the quotient 8 as the next digit in the result. 
Result so far: 91477.598
Subtracting 6776 from 7270 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 12:
The number 847 fits into 4940 5 times, leaving a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 91477.5985
The remainder is 705 after subtracting 4235 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Going ahead to step 13:
If we divide 7050 by 847, we get 8 and a remainder of 274.
Record the quotient 8 as the next digit in the result. 
Result so far: 91477.59858
Subtracting 6776 from 7050 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 14:
The number 847 fits into 2740 3 times, leaving a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 91477.598583
Subtract 2541 from 2740 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 15:
If we divide 1990 by 847, we get 2 and a remainder of 296.
Use 2 as the next digit of our solution. 
Result so far: 91477.5985832
Subtract 1694 from 1990 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 16:
847 goes into 2960 3 times with a remainder of 419.
The next digit of our result is 3. 
Result so far: 91477.59858323
If we subtract 2541 from 2960, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

The final outcome is 91477.59858323, with a leftover of 4.19e-07.
