34231916 ÷ 781 
The aim is to understand the frequency of 781 in 34231916.

Step 1:
When dividing 3 by 781, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 781

Moving on to step 2:
781 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 781

Going ahead to step 3:
781 can be fit into 342 0 times, resulting in a remainder of 342.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 342 to get 342.
Append the next digit (3) from the dividend to 342 and continue with: 3423 / 781

Going ahead to step 4:
If we divide 3423 by 781, we get 4 and a remainder of 299.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3124 from 3423 leaves us with 299.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 781

Let's proceed to step 5:
2991 divided by 781 is 3 with a remainder of 648.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 2343 away from 2991, we end up with 648.
Include the next digit (9) from the dividend after 648, then repeat: 6489 / 781

Going ahead to step 6:
If we divide 6489 by 781, we get 8 and a remainder of 241.
The next digit of our result is 8. 
Result so far: 438.0
The remainder is 241 after subtracting 6248 from 6489.
Append the next digit (1) from the dividend to 241 and continue with: 2411 / 781

Going ahead to step 7:
2411 divided by 781 is 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 4383.0
If we take 2343 away from 2411, we end up with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 781

Step 8:
The number 781 fits into 686 0 times, leaving a remainder of 686.
Write down 0 as next digit of the result. 
Result so far: 43830.0
Subtract 0 from 686 to get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 9:
781 goes into 6860 8 times with a remainder of 612.
The number 8 becomes the next digit in our result. 
Result so far: 43830.8
The remainder is 612 after subtracting 6248 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 10:
When dividing 6120 by 781, we get 7 with a remainder of 653.
Write down 7 as next digit of the result. 
Result so far: 43830.87
Subtracting 5467 from 6120 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 11:
If we divide 6530 by 781, we get 8 and a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 43830.878
Deduct 6248 from 6530 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 12:
2820 divided by 781 is 3 with a remainder of 477.
Put 3 as the next digit of the answer. 
Result so far: 43830.8783
If we take 2343 away from 2820, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 13:
When dividing 4770 by 781, we get 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 43830.87836
If we take 4686 away from 4770, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
The number 781 fits into 840 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 43830.878361
Subtracting 781 from 840 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 15:
The number 781 fits into 590 0 times, leaving a remainder of 590.
Use 0 as the next digit of our solution. 
Result so far: 43830.878361
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 16:
When dividing 5900 by 781, we get 7 with a remainder of 433.
Write down 7 as next digit of the result. 
Result so far: 43830.87836107
The remainder is 433 after subtracting 5467 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

The final outcome is 43830.87836107, with a leftover of 4.33e-07.
