We look at the division of 56090244 by 771 
The aim is to understand the frequency of 771 in 56090244.

Advancing to step 1:
If we divide 5 by 771, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 771

Moving on to step 2:
If we divide 56 by 771, we get 0 and a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 771

On to step 3:
771 can be fit into 560 0 times, resulting in a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 560, we get 560.
Append the next digit (9) from the dividend to 560 and continue with: 5609 / 771

Going ahead to step 4:
771 goes into 5609 7 times with a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5397 from 5609 and we're left with 212.
Grab the next digit (0) from the dividend, add it to 212, then carry on: 2120 / 771

Going ahead to step 5:
The number 771 fits into 2120 2 times, leaving a remainder of 578.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 578 after subtracting 1542 from 2120.
Bring next digit (2) of the dividend behind the 578 and repeat the process: 5782 / 771

Going ahead to step 6:
5782 divided by 771 is 7 with a remainder of 385.
Put 7 as the next digit of the answer. 
Result so far: 727.0
Deduct 5397 from 5782 and we're left with 385.
Include the next digit (4) from the dividend after 385, then repeat: 3854 / 771

On to step 7:
If we divide 3854 by 771, we get 4 and a remainder of 770.
Put 4 as the next digit of the answer. 
Result so far: 7274.0
Subtract 3084 from 3854 to get 770.
Append the next digit (4) from the dividend to 770 and continue with: 7704 / 771

Advancing to step 8:
771 goes into 7704 9 times with a remainder of 765.
The next digit of our result is 9. 
Result so far: 72749.0
Subtracting 6939 from 7704 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Step 9:
When dividing 7650 by 771, we get 9 with a remainder of 711.
The next digit of our result is 9. 
Result so far: 72749.9
Subtracting 6939 from 7650 leaves us with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Step 10:
When dividing 7110 by 771, we get 9 with a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 72749.99
Subtract 6939 from 7110 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Our division results in 72749.99 with a remaining 0.171.
