We look at the division of 33787613 by 781 
The aim is to understand the frequency of 781 in 33787613.

Moving on to step 1:
When dividing 3 by 781, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 781

Advancing to step 2:
781 goes into 33 0 times with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 781

Advancing to step 3:
337 divided by 781 is 0 with a remainder of 337.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 337, we end up with 337.
Take the next digit (8) from the dividend and append it to 337, then repeat: 3378 / 781

Advancing to step 4:
781 goes into 3378 4 times with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 254 after subtracting 3124 from 3378.
Include the next digit (7) from the dividend after 254, then repeat: 2547 / 781

Advancing to step 5:
When dividing 2547 by 781, we get 3 with a remainder of 204.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 2343 from 2547 to get 204.
Fetch the next digit (6) from the dividend, attach it to 204 and continue: 2046 / 781

On to step 6:
781 goes into 2046 2 times with a remainder of 484.
Write down 2 as next digit of the result. 
Result so far: 432.0
If we take 1562 away from 2046, we end up with 484.
Bring next digit (1) of the dividend behind the 484 and repeat the process: 4841 / 781

Going ahead to step 7:
If we divide 4841 by 781, we get 6 and a remainder of 155.
Put 6 as the next digit of the answer. 
Result so far: 4326.0
Subtract 4686 from 4841 to get 155.
Take the next digit (3) from the dividend and append it to 155, then repeat: 1553 / 781

Advancing to step 8:
If we divide 1553 by 781, we get 1 and a remainder of 772.
Put 1 as the next digit of the answer. 
Result so far: 43261.0
If we subtract 781 from 1553, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

On to step 9:
781 goes into 7720 9 times with a remainder of 691.
Record the quotient 9 as the next digit in the result. 
Result so far: 43261.9
Subtract 7029 from 7720 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Going ahead to step 10:
If we divide 6910 by 781, we get 8 and a remainder of 662.
Use 8 as the next digit of our solution. 
Result so far: 43261.98
The remainder is 662 after subtracting 6248 from 6910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 11:
6620 divided by 781 is 8 with a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 43261.988
Subtract 6248 from 6620 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 43261.988 and a remainder of 0.0372.
