Let's divide 81850951 by 659
The aim is to understand the frequency of 659 in 81850951.

Step 1:
If we divide 8 by 659, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 659

On to step 2:
When dividing 81 by 659, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 659

On to step 3:
659 goes into 818 1 times with a remainder of 159.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 159 after subtracting 659 from 818.
Grab the next digit (5) from the dividend, add it to 159, then carry on: 1595 / 659

Moving on to step 4:
1595 divided by 659 is 2 with a remainder of 277.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1318 from 1595, we get 277.
Fetch the next digit (0) from the dividend, attach it to 277 and continue: 2770 / 659

Let's proceed to step 5:
When dividing 2770 by 659, we get 4 with a remainder of 134.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we take 2636 away from 2770, we end up with 134.
Bring next digit (9) of the dividend behind the 134 and repeat the process: 1349 / 659

On to step 6:
659 goes into 1349 2 times with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 1242.0
If we take 1318 away from 1349, we end up with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 659

Moving on to step 7:
315 divided by 659 is 0 with a remainder of 315.
Use 0 as the next digit of our solution. 
Result so far: 12420.0
Subtract 0 from 315 to get 315.
Include the next digit (1) from the dividend after 315, then repeat: 3151 / 659

Going ahead to step 8:
If we divide 3151 by 659, we get 4 and a remainder of 515.
Use 4 as the next digit of our solution. 
Result so far: 124204.0
The remainder is 515 after subtracting 2636 from 3151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 9:
5150 divided by 659 is 7 with a remainder of 537.
Write down 7 as next digit of the result. 
Result so far: 124204.7
Deduct 4613 from 5150 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Going ahead to step 10:
5370 divided by 659 is 8 with a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 124204.78
Deduct 5272 from 5370 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 11:
If we divide 980 by 659, we get 1 and a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 124204.781
Subtract 659 from 980 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 12:
The number 659 fits into 3210 4 times, leaving a remainder of 574.
Record the quotient 4 as the next digit in the result. 
Result so far: 124204.7814
Subtract 2636 from 3210 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 13:
If we divide 5740 by 659, we get 8 and a remainder of 468.
The number 8 becomes the next digit in our result. 
Result so far: 124204.78148
Deduct 5272 from 5740 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 14:
If we divide 4680 by 659, we get 7 and a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 124204.781487
The remainder is 67 after subtracting 4613 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 15:
659 can be fit into 670 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 124204.7814871
If we take 659 away from 670, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 16:
110 divided by 659 is 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 124204.7814871
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 124204.7814871 with a balance of 1.1e-07.
