We're dividing 25086491 by 659 
The aim is to understand the frequency of 659 in 25086491.

Going ahead to step 1:
659 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 659

Moving on to step 2:
The number 659 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 659

Going ahead to step 3:
The number 659 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 250, we end up with 250.
Bring next digit (8) of the dividend behind the 250 and repeat the process: 2508 / 659

Moving on to step 4:
If we divide 2508 by 659, we get 3 and a remainder of 531.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1977 from 2508 to get 531.
Take the next digit (6) from the dividend and append it to 531, then repeat: 5316 / 659

On to step 5:
The number 659 fits into 5316 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 5272 away from 5316, we end up with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 659

On to step 6:
If we divide 444 by 659, we get 0 and a remainder of 444.
The next digit of our result is 0. 
Result so far: 380.0
The remainder is 444 after subtracting 0 from 444.
Take the next digit (9) from the dividend and append it to 444, then repeat: 4449 / 659

Going ahead to step 7:
659 goes into 4449 6 times with a remainder of 495.
Put 6 as the next digit of the answer. 
Result so far: 3806.0
Subtracting 3954 from 4449 leaves us with 495.
Take the next digit (1) from the dividend and append it to 495, then repeat: 4951 / 659

Let's proceed to step 8:
The number 659 fits into 4951 7 times, leaving a remainder of 338.
Record the quotient 7 as the next digit in the result. 
Result so far: 38067.0
If we take 4613 away from 4951, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 9:
When dividing 3380 by 659, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 38067.5
Deduct 3295 from 3380 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 10:
850 divided by 659 is 1 with a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 38067.51
If we subtract 659 from 850, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 11:
1910 divided by 659 is 2 with a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 38067.512
If we subtract 1318 from 1910, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 12:
659 goes into 5920 8 times with a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 38067.5128
If we subtract 5272 from 5920, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 13:
6480 divided by 659 is 9 with a remainder of 549.
The number 9 becomes the next digit in our result. 
Result so far: 38067.51289
Deduct 5931 from 6480 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Advancing to step 14:
If we divide 5490 by 659, we get 8 and a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 38067.512898
The remainder is 218 after subtracting 5272 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
If we divide 2180 by 659, we get 3 and a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 38067.5128983
Deduct 1977 from 2180 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 16:
When dividing 2030 by 659, we get 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 38067.51289833
The remainder is 53 after subtracting 1977 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 38067.51289833 and a remainder of 5.3e-08.
