We're dividing 15123790 by 613 
The aim is to understand the frequency of 613 in 15123790.

Let's proceed to step 1:
If we divide 1 by 613, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 613

Moving on to step 2:
If we divide 15 by 613, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 613

Advancing to step 3:
When dividing 151 by 613, we get 0 with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Fetch the next digit (2) from the dividend, attach it to 151 and continue: 1512 / 613

Going ahead to step 4:
If we divide 1512 by 613, we get 2 and a remainder of 286.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1226 away from 1512, we end up with 286.
Append the next digit (3) from the dividend to 286 and continue with: 2863 / 613

On to step 5:
613 can be fit into 2863 4 times, resulting in a remainder of 411.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 2452 from 2863 and we're left with 411.
Grab the next digit (7) from the dividend, add it to 411, then carry on: 4117 / 613

Step 6:
4117 divided by 613 is 6 with a remainder of 439.
The number 6 becomes the next digit in our result. 
Result so far: 246.0
Subtracting 3678 from 4117 leaves us with 439.
Bring next digit (9) of the dividend behind the 439 and repeat the process: 4399 / 613

Going ahead to step 7:
When dividing 4399 by 613, we get 7 with a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 2467.0
Subtracting 4291 from 4399 leaves us with 108.
Bring next digit (0) of the dividend behind the 108 and repeat the process: 1080 / 613

Advancing to step 8:
The number 613 fits into 1080 1 times, leaving a remainder of 467.
Record the quotient 1 as the next digit in the result. 
Result so far: 24671.0
The remainder is 467 after subtracting 613 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 9:
613 can be fit into 4670 7 times, resulting in a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 24671.7
Subtract 4291 from 4670 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 10:
613 can be fit into 3790 6 times, resulting in a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 24671.76
The remainder is 112 after subtracting 3678 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
The number 613 fits into 1120 1 times, leaving a remainder of 507.
The next digit of our result is 1. 
Result so far: 24671.761
If we take 613 away from 1120, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 12:
5070 divided by 613 is 8 with a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 24671.7618
If we take 4904 away from 5070, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 13:
613 can be fit into 1660 2 times, resulting in a remainder of 434.
Use 2 as the next digit of our solution. 
Result so far: 24671.76182
The remainder is 434 after subtracting 1226 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 14:
4340 divided by 613 is 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 24671.761827
Deduct 4291 from 4340 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 15:
613 goes into 490 0 times with a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 24671.761827
Subtract 0 from 490 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 16:
If we divide 4900 by 613, we get 7 and a remainder of 609.
The next digit of our result is 7. 
Result so far: 24671.76182707
Subtract 4291 from 4900 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Our division results in 24671.76182707 with a remaining 6.09e-07.
