Let's divide 15858430 by 773
The aim is to understand the frequency of 773 in 15858430.

Let's proceed to step 1:
1 divided by 773 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 773

Step 2:
773 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 773

Let's proceed to step 3:
773 goes into 158 0 times with a remainder of 158.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Grab the next digit (5) from the dividend, add it to 158, then carry on: 1585 / 773

Advancing to step 4:
When dividing 1585 by 773, we get 2 with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1546 from 1585, we get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 773

Going ahead to step 5:
The number 773 fits into 398 0 times, leaving a remainder of 398.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 398 leaves us with 398.
Fetch the next digit (4) from the dividend, attach it to 398 and continue: 3984 / 773

Moving on to step 6:
773 can be fit into 3984 5 times, resulting in a remainder of 119.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtract 3865 from 3984 to get 119.
Take the next digit (3) from the dividend and append it to 119, then repeat: 1193 / 773

Step 7:
If we divide 1193 by 773, we get 1 and a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 2051.0
Subtracting 773 from 1193 leaves us with 420.
Fetch the next digit (0) from the dividend, attach it to 420 and continue: 4200 / 773

On to step 8:
773 goes into 4200 5 times with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 20515.0
Subtracting 3865 from 4200 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 9:
773 goes into 3350 4 times with a remainder of 258.
Put 4 as the next digit of the answer. 
Result so far: 20515.4
The remainder is 258 after subtracting 3092 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 10:
773 can be fit into 2580 3 times, resulting in a remainder of 261.
Record the quotient 3 as the next digit in the result. 
Result so far: 20515.43
The remainder is 261 after subtracting 2319 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 11:
773 goes into 2610 3 times with a remainder of 291.
Write down 3 as next digit of the result. 
Result so far: 20515.433
If we subtract 2319 from 2610, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

The final outcome is 20515.433, with a leftover of 0.0291.
