We look at the division of 32156393 by 781 
The aim is to understand the frequency of 781 in 32156393.

Step 1:
When dividing 3 by 781, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 781

Going ahead to step 2:
781 goes into 32 0 times with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 781

Let's proceed to step 3:
When dividing 321 by 781, we get 0 with a remainder of 321.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 321, we get 321.
Bring next digit (5) of the dividend behind the 321 and repeat the process: 3215 / 781

Step 4:
The number 781 fits into 3215 4 times, leaving a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3124 from 3215 and we're left with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 781

Let's proceed to step 5:
781 can be fit into 916 1 times, resulting in a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 781 from 916 to get 135.
Fetch the next digit (3) from the dividend, attach it to 135 and continue: 1353 / 781

Going ahead to step 6:
781 can be fit into 1353 1 times, resulting in a remainder of 572.
The next digit of our result is 1. 
Result so far: 411.0
The remainder is 572 after subtracting 781 from 1353.
Take the next digit (9) from the dividend and append it to 572, then repeat: 5729 / 781

Advancing to step 7:
781 can be fit into 5729 7 times, resulting in a remainder of 262.
Use 7 as the next digit of our solution. 
Result so far: 4117.0
Subtract 5467 from 5729 to get 262.
Append the next digit (3) from the dividend to 262 and continue with: 2623 / 781

Advancing to step 8:
If we divide 2623 by 781, we get 3 and a remainder of 280.
The next digit of our result is 3. 
Result so far: 41173.0
If we subtract 2343 from 2623, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 9:
The number 781 fits into 2800 3 times, leaving a remainder of 457.
Put 3 as the next digit of the answer. 
Result so far: 41173.3
If we take 2343 away from 2800, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 10:
If we divide 4570 by 781, we get 5 and a remainder of 665.
Use 5 as the next digit of our solution. 
Result so far: 41173.35
Subtracting 3905 from 4570 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Moving on to step 11:
781 can be fit into 6650 8 times, resulting in a remainder of 402.
Use 8 as the next digit of our solution. 
Result so far: 41173.358
Subtract 6248 from 6650 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 12:
The number 781 fits into 4020 5 times, leaving a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 41173.3585
If we subtract 3905 from 4020, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 13:
1150 divided by 781 is 1 with a remainder of 369.
Record the quotient 1 as the next digit in the result. 
Result so far: 41173.35851
If we take 781 away from 1150, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 14:
3690 divided by 781 is 4 with a remainder of 566.
Put 4 as the next digit of the answer. 
Result so far: 41173.358514
Deduct 3124 from 3690 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 15:
The number 781 fits into 5660 7 times, leaving a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 41173.3585147
Deduct 5467 from 5660 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 16:
781 can be fit into 1930 2 times, resulting in a remainder of 368.
Use 2 as the next digit of our solution. 
Result so far: 41173.35851472
Subtract 1562 from 1930 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 41173.35851472 with a remainder of 3.68e-07.
