We look at the division of 55749972 by 782 
The aim is to understand the frequency of 782 in 55749972.

Step 1:
782 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 782

Going ahead to step 2:
782 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 782

Let's proceed to step 3:
If we divide 557 by 782, we get 0 and a remainder of 557.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 557, we end up with 557.
Append the next digit (4) from the dividend to 557 and continue with: 5574 / 782

Moving on to step 4:
If we divide 5574 by 782, we get 7 and a remainder of 100.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 5474 from 5574 and we're left with 100.
Fetch the next digit (9) from the dividend, attach it to 100 and continue: 1009 / 782

Let's proceed to step 5:
If we divide 1009 by 782, we get 1 and a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 782 away from 1009, we end up with 227.
Take the next digit (9) from the dividend and append it to 227, then repeat: 2279 / 782

Let's proceed to step 6:
782 can be fit into 2279 2 times, resulting in a remainder of 715.
Use 2 as the next digit of our solution. 
Result so far: 712.0
Deduct 1564 from 2279 and we're left with 715.
Fetch the next digit (7) from the dividend, attach it to 715 and continue: 7157 / 782

On to step 7:
If we divide 7157 by 782, we get 9 and a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 7129.0
Deduct 7038 from 7157 and we're left with 119.
Grab the next digit (2) from the dividend, add it to 119, then carry on: 1192 / 782

Advancing to step 8:
If we divide 1192 by 782, we get 1 and a remainder of 410.
The next digit of our result is 1. 
Result so far: 71291.0
The remainder is 410 after subtracting 782 from 1192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 9:
782 goes into 4100 5 times with a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 71291.5
Deduct 3910 from 4100 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
When dividing 1900 by 782, we get 2 with a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 71291.52
If we take 1564 away from 1900, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 11:
When dividing 3360 by 782, we get 4 with a remainder of 232.
Put 4 as the next digit of the answer. 
Result so far: 71291.524
Deduct 3128 from 3360 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 12:
782 can be fit into 2320 2 times, resulting in a remainder of 756.
Use 2 as the next digit of our solution. 
Result so far: 71291.5242
The remainder is 756 after subtracting 1564 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 13:
The number 782 fits into 7560 9 times, leaving a remainder of 522.
The number 9 becomes the next digit in our result. 
Result so far: 71291.52429
The remainder is 522 after subtracting 7038 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 14:
When dividing 5220 by 782, we get 6 with a remainder of 528.
The next digit of our result is 6. 
Result so far: 71291.524296
Deduct 4692 from 5220 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 15:
782 can be fit into 5280 6 times, resulting in a remainder of 588.
Put 6 as the next digit of the answer. 
Result so far: 71291.5242966
If we subtract 4692 from 5280, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

The final result is 71291.5242966 with a remainder of 5.88e-06.
