We're dividing 79201573 by 781 
The aim is to understand the frequency of 781 in 79201573.

Step 1:
7 divided by 781 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 781

On to step 2:
781 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Include the next digit (2) from the dividend after 79, then repeat: 792 / 781

Step 3:
781 can be fit into 792 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 781 from 792 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 781

Moving on to step 4:
781 goes into 110 0 times with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 110, we get 110.
Grab the next digit (1) from the dividend, add it to 110, then carry on: 1101 / 781

Going ahead to step 5:
When dividing 1101 by 781, we get 1 with a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 781 away from 1101, we end up with 320.
Bring next digit (5) of the dividend behind the 320 and repeat the process: 3205 / 781

Moving on to step 6:
3205 divided by 781 is 4 with a remainder of 81.
The next digit of our result is 4. 
Result so far: 1014.0
If we subtract 3124 from 3205, we get 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 781

Step 7:
781 goes into 817 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 10141.0
Deduct 781 from 817 and we're left with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 781

Going ahead to step 8:
If we divide 363 by 781, we get 0 and a remainder of 363.
Write down 0 as next digit of the result. 
Result so far: 101410.0
If we take 0 away from 363, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 9:
When dividing 3630 by 781, we get 4 with a remainder of 506.
Record the quotient 4 as the next digit in the result. 
Result so far: 101410.4
If we subtract 3124 from 3630, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 10:
The number 781 fits into 5060 6 times, leaving a remainder of 374.
Use 6 as the next digit of our solution. 
Result so far: 101410.46
If we subtract 4686 from 5060, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 11:
If we divide 3740 by 781, we get 4 and a remainder of 616.
The next digit of our result is 4. 
Result so far: 101410.464
Subtracting 3124 from 3740 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 12:
When dividing 6160 by 781, we get 7 with a remainder of 693.
The next digit of our result is 7. 
Result so far: 101410.4647
Deduct 5467 from 6160 and we're left with 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Advancing to step 13:
781 can be fit into 6930 8 times, resulting in a remainder of 682.
The number 8 becomes the next digit in our result. 
Result so far: 101410.46478
The remainder is 682 after subtracting 6248 from 6930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Advancing to step 14:
If we divide 6820 by 781, we get 8 and a remainder of 572.
The number 8 becomes the next digit in our result. 
Result so far: 101410.464788
Subtract 6248 from 6820 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The quotient of the division is 101410.464788, and the remainder is 5.72e-05.
