We're dividing 19770778 by 513 
The aim is to understand the frequency of 513 in 19770778.

Let's proceed to step 1:
513 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 513

Advancing to step 2:
If we divide 19 by 513, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 513

Going ahead to step 3:
When dividing 197 by 513, we get 0 with a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Grab the next digit (7) from the dividend, add it to 197, then carry on: 1977 / 513

On to step 4:
If we divide 1977 by 513, we get 3 and a remainder of 438.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1539 from 1977, we get 438.
Fetch the next digit (0) from the dividend, attach it to 438 and continue: 4380 / 513

On to step 5:
The number 513 fits into 4380 8 times, leaving a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we subtract 4104 from 4380, we get 276.
Grab the next digit (7) from the dividend, add it to 276, then carry on: 2767 / 513

Advancing to step 6:
If we divide 2767 by 513, we get 5 and a remainder of 202.
The next digit of our result is 5. 
Result so far: 385.0
If we subtract 2565 from 2767, we get 202.
Grab the next digit (7) from the dividend, add it to 202, then carry on: 2027 / 513

On to step 7:
513 goes into 2027 3 times with a remainder of 488.
Record the quotient 3 as the next digit in the result. 
Result so far: 3853.0
Subtracting 1539 from 2027 leaves us with 488.
Take the next digit (8) from the dividend and append it to 488, then repeat: 4888 / 513

Moving on to step 8:
When dividing 4888 by 513, we get 9 with a remainder of 271.
The next digit of our result is 9. 
Result so far: 38539.0
Subtract 4617 from 4888 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 9:
513 goes into 2710 5 times with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 38539.5
Subtracting 2565 from 2710 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 10:
If we divide 1450 by 513, we get 2 and a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 38539.52
Deduct 1026 from 1450 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 11:
If we divide 4240 by 513, we get 8 and a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 38539.528
If we take 4104 away from 4240, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
The number 513 fits into 1360 2 times, leaving a remainder of 334.
The next digit of our result is 2. 
Result so far: 38539.5282
The remainder is 334 after subtracting 1026 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 13:
513 goes into 3340 6 times with a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 38539.52826
If we take 3078 away from 3340, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 14:
513 goes into 2620 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 38539.528265
Subtract 2565 from 2620 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 15:
If we divide 550 by 513, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 38539.5282651
If we take 513 away from 550, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 16:
370 divided by 513 is 0 with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 38539.5282651
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The quotient of the division is 38539.5282651, and the remainder is 3.7e-07.
