Let's divide 81537127 by 617
The aim is to understand the frequency of 617 in 81537127.

Going ahead to step 1:
617 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 617

Let's proceed to step 2:
The number 617 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 617

On to step 3:
When dividing 815 by 617, we get 1 with a remainder of 198.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 617 from 815 to get 198.
Append the next digit (3) from the dividend to 198 and continue with: 1983 / 617

Advancing to step 4:
If we divide 1983 by 617, we get 3 and a remainder of 132.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1851 from 1983 and we're left with 132.
Grab the next digit (7) from the dividend, add it to 132, then carry on: 1327 / 617

Moving on to step 5:
When dividing 1327 by 617, we get 2 with a remainder of 93.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 1234 away from 1327, we end up with 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 617

Step 6:
The number 617 fits into 931 1 times, leaving a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 1321.0
Subtract 617 from 931 to get 314.
Bring next digit (2) of the dividend behind the 314 and repeat the process: 3142 / 617

On to step 7:
If we divide 3142 by 617, we get 5 and a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 13215.0
If we take 3085 away from 3142, we end up with 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 617

Going ahead to step 8:
The number 617 fits into 577 0 times, leaving a remainder of 577.
Put 0 as the next digit of the answer. 
Result so far: 132150.0
If we subtract 0 from 577, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 9:
617 goes into 5770 9 times with a remainder of 217.
Put 9 as the next digit of the answer. 
Result so far: 132150.9
Deduct 5553 from 5770 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 10:
The number 617 fits into 2170 3 times, leaving a remainder of 319.
Put 3 as the next digit of the answer. 
Result so far: 132150.93
If we take 1851 away from 2170, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 11:
617 can be fit into 3190 5 times, resulting in a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 132150.935
Subtracting 3085 from 3190 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 12:
When dividing 1050 by 617, we get 1 with a remainder of 433.
The number 1 becomes the next digit in our result. 
Result so far: 132150.9351
The remainder is 433 after subtracting 617 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 13:
617 can be fit into 4330 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 132150.93517
If we subtract 4319 from 4330, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
110 divided by 617 is 0 with a remainder of 110.
The next digit of our result is 0. 
Result so far: 132150.93517
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.

Step 15:
617 can be fit into 1100 1 times, resulting in a remainder of 483.
Use 1 as the next digit of our solution. 
Result so far: 132150.9351701
If we subtract 617 from 1100, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 16:
617 can be fit into 4830 7 times, resulting in a remainder of 511.
Put 7 as the next digit of the answer. 
Result so far: 132150.93517017
If we subtract 4319 from 4830, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

After the division, we end up with 132150.93517017 and a remainder of 5.11e-07.
