We look at the division of 51241856 by 785 
The aim is to understand the frequency of 785 in 51241856.

Going ahead to step 1:
5 divided by 785 is 0 with 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 (1) from the dividend, attach it to 5 and continue: 51 / 785

Step 2:
If we divide 51 by 785, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 785

Advancing to step 3:
If we divide 512 by 785, we get 0 and a remainder of 512.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 512, we get 512.
Take the next digit (4) from the dividend and append it to 512, then repeat: 5124 / 785

Moving on to step 4:
When dividing 5124 by 785, we get 6 with a remainder of 414.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 4710 away from 5124, we end up with 414.
Append the next digit (1) from the dividend to 414 and continue with: 4141 / 785

On to step 5:
4141 divided by 785 is 5 with a remainder of 216.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Deduct 3925 from 4141 and we're left with 216.
Grab the next digit (8) from the dividend, add it to 216, then carry on: 2168 / 785

Step 6:
When dividing 2168 by 785, we get 2 with a remainder of 598.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
Subtracting 1570 from 2168 leaves us with 598.
Bring next digit (5) of the dividend behind the 598 and repeat the process: 5985 / 785

On to step 7:
5985 divided by 785 is 7 with a remainder of 490.
The number 7 becomes the next digit in our result. 
Result so far: 6527.0
Subtracting 5495 from 5985 leaves us with 490.
Grab the next digit (6) from the dividend, add it to 490, then carry on: 4906 / 785

Advancing to step 8:
785 goes into 4906 6 times with a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 65276.0
Subtract 4710 from 4906 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 9:
1960 divided by 785 is 2 with a remainder of 390.
Write down 2 as next digit of the result. 
Result so far: 65276.2
Subtracting 1570 from 1960 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
If we divide 3900 by 785, we get 4 and a remainder of 760.
Write down 4 as next digit of the result. 
Result so far: 65276.24
Subtract 3140 from 3900 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 11:
When dividing 7600 by 785, we get 9 with a remainder of 535.
The next digit of our result is 9. 
Result so far: 65276.249
Deduct 7065 from 7600 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 12:
785 goes into 5350 6 times with a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 65276.2496
Subtracting 4710 from 5350 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 13:
785 can be fit into 6400 8 times, resulting in a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 65276.24968
Subtracting 6280 from 6400 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
1200 divided by 785 is 1 with a remainder of 415.
Put 1 as the next digit of the answer. 
Result so far: 65276.249681
If we subtract 785 from 1200, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 15:
When dividing 4150 by 785, we get 5 with a remainder of 225.
The next digit of our result is 5. 
Result so far: 65276.2496815
Subtracting 3925 from 4150 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 16:
If we divide 2250 by 785, we get 2 and a remainder of 680.
The number 2 becomes the next digit in our result. 
Result so far: 65276.24968152
Deduct 1570 from 2250 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The quotient of the division is 65276.24968152, and the remainder is 6.8e-07.
