We look at the division of 31407333 by 783 
The aim is to understand the frequency of 783 in 31407333.

Step 1:
783 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 783

Step 2:
When dividing 31 by 783, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 783

Let's proceed to step 3:
The number 783 fits into 314 0 times, leaving a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 314, we get 314.
Append the next digit (0) from the dividend to 314 and continue with: 3140 / 783

Let's proceed to step 4:
3140 divided by 783 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3132 from 3140 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 783

Moving on to step 5:
The number 783 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (3) from the dividend, attach it to 87 and continue: 873 / 783

Going ahead to step 6:
783 can be fit into 873 1 times, resulting in a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 401.0
Deduct 783 from 873 and we're left with 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 783

On to step 7:
If we divide 903 by 783, we get 1 and a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 4011.0
Subtracting 783 from 903 leaves us with 120.
Include the next digit (3) from the dividend after 120, then repeat: 1203 / 783

Advancing to step 8:
If we divide 1203 by 783, we get 1 and a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 40111.0
Deduct 783 from 1203 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 9:
783 can be fit into 4200 5 times, resulting in a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 40111.5
If we take 3915 away from 4200, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
The number 783 fits into 2850 3 times, leaving a remainder of 501.
The number 3 becomes the next digit in our result. 
Result so far: 40111.53
Subtracting 2349 from 2850 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 11:
When dividing 5010 by 783, we get 6 with a remainder of 312.
Use 6 as the next digit of our solution. 
Result so far: 40111.536
The remainder is 312 after subtracting 4698 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 12:
3120 divided by 783 is 3 with a remainder of 771.
Put 3 as the next digit of the answer. 
Result so far: 40111.5363
If we take 2349 away from 3120, we end up with 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Advancing to step 13:
The number 783 fits into 7710 9 times, leaving a remainder of 663.
Use 9 as the next digit of our solution. 
Result so far: 40111.53639
Deduct 7047 from 7710 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Moving on to step 14:
When dividing 6630 by 783, we get 8 with a remainder of 366.
Write down 8 as next digit of the result. 
Result so far: 40111.536398
Subtracting 6264 from 6630 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 15:
3660 divided by 783 is 4 with a remainder of 528.
The next digit of our result is 4. 
Result so far: 40111.5363984
If we subtract 3132 from 3660, we get 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 16:
When dividing 5280 by 783, we get 6 with a remainder of 582.
The next digit of our result is 6. 
Result so far: 40111.53639846
If we subtract 4698 from 5280, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

The final outcome is 40111.53639846, with a leftover of 5.82e-07.
