We look at the division of 87560707 by 617 
The aim is to understand the frequency of 617 in 87560707.

Advancing to step 1:
If we divide 8 by 617, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 617

On to step 2:
617 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 617

Moving on to step 3:
617 can be fit into 875 1 times, resulting in a remainder of 258.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 617 from 875 to get 258.
Bring next digit (6) of the dividend behind the 258 and repeat the process: 2586 / 617

Let's proceed to step 4:
If we divide 2586 by 617, we get 4 and a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2468 from 2586, we get 118.
Take the next digit (0) from the dividend and append it to 118, then repeat: 1180 / 617

Let's proceed to step 5:
When dividing 1180 by 617, we get 1 with a remainder of 563.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtracting 617 from 1180 leaves us with 563.
Append the next digit (7) from the dividend to 563 and continue with: 5637 / 617

Let's proceed to step 6:
617 can be fit into 5637 9 times, resulting in a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 1419.0
The remainder is 84 after subtracting 5553 from 5637.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 617

Advancing to step 7:
If we divide 840 by 617, we get 1 and a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 14191.0
The remainder is 223 after subtracting 617 from 840.
Bring next digit (7) of the dividend behind the 223 and repeat the process: 2237 / 617

Step 8:
If we divide 2237 by 617, we get 3 and a remainder of 386.
The next digit of our result is 3. 
Result so far: 141913.0
Subtract 1851 from 2237 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 9:
If we divide 3860 by 617, we get 6 and a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 141913.6
Subtract 3702 from 3860 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
If we divide 1580 by 617, we get 2 and a remainder of 346.
Write down 2 as next digit of the result. 
Result so far: 141913.62
Deduct 1234 from 1580 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 11:
The number 617 fits into 3460 5 times, leaving a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 141913.625
Subtracting 3085 from 3460 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 12:
When dividing 3750 by 617, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 141913.6256
The remainder is 48 after subtracting 3702 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
The number 617 fits into 480 0 times, leaving a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 141913.6256
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
The number 617 fits into 4800 7 times, leaving a remainder of 481.
The number 7 becomes the next digit in our result. 
Result so far: 141913.625607
If we take 4319 away from 4800, we end up with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 15:
4810 divided by 617 is 7 with a remainder of 491.
Use 7 as the next digit of our solution. 
Result so far: 141913.6256077
If we subtract 4319 from 4810, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

After the division, we end up with 141913.6256077 and a remainder of 4.91e-06.
