3937063 divided by 782 
The aim is to understand the frequency of 782 in 3937063.

Step 1:
If we divide 3 by 782, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 782

Step 2:
When dividing 39 by 782, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 782

Going ahead to step 3:
When dividing 393 by 782, we get 0 with a remainder of 393.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Bring next digit (7) of the dividend behind the 393 and repeat the process: 3937 / 782

Going ahead to step 4:
3937 divided by 782 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 3910 from 3937, we get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 782

Let's proceed to step 5:
782 goes into 270 0 times with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 270 to get 270.
Grab the next digit (6) from the dividend, add it to 270, then carry on: 2706 / 782

Moving on to step 6:
2706 divided by 782 is 3 with a remainder of 360.
Use 3 as the next digit of our solution. 
Result so far: 503.0
Deduct 2346 from 2706 and we're left with 360.
Grab the next digit (3) from the dividend, add it to 360, then carry on: 3603 / 782

On to step 7:
When dividing 3603 by 782, we get 4 with a remainder of 475.
The next digit of our result is 4. 
Result so far: 5034.0
The remainder is 475 after subtracting 3128 from 3603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 8:
The number 782 fits into 4750 6 times, leaving a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 5034.6
Subtract 4692 from 4750 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
782 goes into 580 0 times with a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 5034.6
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 10:
The number 782 fits into 5800 7 times, leaving a remainder of 326.
Put 7 as the next digit of the answer. 
Result so far: 5034.607
The remainder is 326 after subtracting 5474 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 11:
The number 782 fits into 3260 4 times, leaving a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 5034.6074
If we subtract 3128 from 3260, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
782 goes into 1320 1 times with a remainder of 538.
Record the quotient 1 as the next digit in the result. 
Result so far: 5034.60741
Deduct 782 from 1320 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 13:
5380 divided by 782 is 6 with a remainder of 688.
The number 6 becomes the next digit in our result. 
Result so far: 5034.607416
The remainder is 688 after subtracting 4692 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 14:
782 can be fit into 6880 8 times, resulting in a remainder of 624.
The number 8 becomes the next digit in our result. 
Result so far: 5034.6074168
If we subtract 6256 from 6880, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 15:
When dividing 6240 by 782, we get 7 with a remainder of 766.
The next digit of our result is 7. 
Result so far: 5034.60741687
Subtract 5474 from 6240 to get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

The final outcome is 5034.60741687, with a leftover of 7.66e-07.
