Let's divide 39493757 by 517
The aim is to understand the frequency of 517 in 39493757.

Let's proceed to step 1:
When dividing 3 by 517, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 517

On to step 2:
The number 517 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 517

Moving on to step 3:
517 can be fit into 394 0 times, resulting in a remainder of 394.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 394 to get 394.
Bring next digit (9) of the dividend behind the 394 and repeat the process: 3949 / 517

Going ahead to step 4:
The number 517 fits into 3949 7 times, leaving a remainder of 330.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 3619 from 3949 and we're left with 330.
Take the next digit (3) from the dividend and append it to 330, then repeat: 3303 / 517

On to step 5:
The number 517 fits into 3303 6 times, leaving a remainder of 201.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 3102 away from 3303, we end up with 201.
Bring next digit (7) of the dividend behind the 201 and repeat the process: 2017 / 517

On to step 6:
517 can be fit into 2017 3 times, resulting in a remainder of 466.
The number 3 becomes the next digit in our result. 
Result so far: 763.0
Deduct 1551 from 2017 and we're left with 466.
Take the next digit (5) from the dividend and append it to 466, then repeat: 4665 / 517

Advancing to step 7:
The number 517 fits into 4665 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 7639.0
Subtract 4653 from 4665 to get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 517

Moving on to step 8:
127 divided by 517 is 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 76390.0
Subtracting 0 from 127 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 9:
If we divide 1270 by 517, we get 2 and a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 76390.2
If we subtract 1034 from 1270, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 10:
If we divide 2360 by 517, we get 4 and a remainder of 292.
Write down 4 as next digit of the result. 
Result so far: 76390.24
If we subtract 2068 from 2360, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 11:
2920 divided by 517 is 5 with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 76390.245
The remainder is 335 after subtracting 2585 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 12:
When dividing 3350 by 517, we get 6 with a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 76390.2456
Deduct 3102 from 3350 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
If we divide 2480 by 517, we get 4 and a remainder of 412.
Write down 4 as next digit of the result. 
Result so far: 76390.24564
Deduct 2068 from 2480 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 14:
If we divide 4120 by 517, we get 7 and a remainder of 501.
The next digit of our result is 7. 
Result so far: 76390.245647
If we take 3619 away from 4120, we end up 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.

On to step 15:
The number 517 fits into 5010 9 times, leaving a remainder of 357.
The number 9 becomes the next digit in our result. 
Result so far: 76390.2456479
Subtract 4653 from 5010 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 16:
When dividing 3570 by 517, we get 6 with a remainder of 468.
Record the quotient 6 as the next digit in the result. 
Result so far: 76390.24564796
Subtract 3102 from 3570 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Our division results in 76390.24564796 with a remaining 4.68e-07.
