We're dividing 61931748 by 807 
The aim is to understand the frequency of 807 in 61931748.

Let's proceed to step 1:
If we divide 6 by 807, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 807

On to step 2:
807 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 807

Let's proceed to step 3:
The number 807 fits into 619 0 times, leaving a remainder of 619.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 619, we get 619.
Bring next digit (3) of the dividend behind the 619 and repeat the process: 6193 / 807

Going ahead to step 4:
807 goes into 6193 7 times with a remainder of 544.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5649 from 6193 to get 544.
Fetch the next digit (1) from the dividend, attach it to 544 and continue: 5441 / 807

Step 5:
The number 807 fits into 5441 6 times, leaving a remainder of 599.
The next digit of our result is 6. 
Result so far: 76.0
If we subtract 4842 from 5441, we get 599.
Append the next digit (7) from the dividend to 599 and continue with: 5997 / 807

On to step 6:
5997 divided by 807 is 7 with a remainder of 348.
Record the quotient 7 as the next digit in the result. 
Result so far: 767.0
If we subtract 5649 from 5997, we get 348.
Include the next digit (4) from the dividend after 348, then repeat: 3484 / 807

Let's proceed to step 7:
When dividing 3484 by 807, we get 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 7674.0
Subtracting 3228 from 3484 leaves us with 256.
Bring next digit (8) of the dividend behind the 256 and repeat the process: 2568 / 807

Let's proceed to step 8:
When dividing 2568 by 807, we get 3 with a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 76743.0
If we take 2421 away from 2568, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 9:
807 goes into 1470 1 times with a remainder of 663.
The next digit of our result is 1. 
Result so far: 76743.1
Subtract 807 from 1470 to get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

On to step 10:
If we divide 6630 by 807, we get 8 and a remainder of 174.
The next digit of our result is 8. 
Result so far: 76743.18
Subtract 6456 from 6630 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
807 can be fit into 1740 2 times, resulting in a remainder of 126.
Put 2 as the next digit of the answer. 
Result so far: 76743.182
Deduct 1614 from 1740 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 12:
The number 807 fits into 1260 1 times, leaving a remainder of 453.
The next digit of our result is 1. 
Result so far: 76743.1821
Subtract 807 from 1260 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 13:
When dividing 4530 by 807, we get 5 with a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 76743.18215
Deduct 4035 from 4530 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 14:
If we divide 4950 by 807, we get 6 and a remainder of 108.
The next digit of our result is 6. 
Result so far: 76743.182156
The remainder is 108 after subtracting 4842 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 15:
807 can be fit into 1080 1 times, resulting in a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 76743.1821561
Subtracting 807 from 1080 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 16:
When dividing 2730 by 807, we get 3 with a remainder of 309.
Put 3 as the next digit of the answer. 
Result so far: 76743.18215613
The remainder is 309 after subtracting 2421 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

After the division, we end up with 76743.18215613 and a remainder of 3.09e-07.
