16656639 ÷ 617 
The aim is to understand the frequency of 617 in 16656639.

Let's proceed to step 1:
When dividing 1 by 617, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 617

Step 2:
If we divide 16 by 617, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 617

Moving on to step 3:
If we divide 166 by 617, we get 0 and a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 166, we get 166.
Bring next digit (5) of the dividend behind the 166 and repeat the process: 1665 / 617

On to step 4:
617 can be fit into 1665 2 times, resulting in a remainder of 431.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 431 after subtracting 1234 from 1665.
Fetch the next digit (6) from the dividend, attach it to 431 and continue: 4316 / 617

Step 5:
If we divide 4316 by 617, we get 6 and a remainder of 614.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 3702 from 4316 and we're left with 614.
Append the next digit (6) from the dividend to 614 and continue with: 6146 / 617

Going ahead to step 6:
The number 617 fits into 6146 9 times, leaving a remainder of 593.
Write down 9 as next digit of the result. 
Result so far: 269.0
Subtracting 5553 from 6146 leaves us with 593.
Take the next digit (3) from the dividend and append it to 593, then repeat: 5933 / 617

Let's proceed to step 7:
When dividing 5933 by 617, we get 9 with a remainder of 380.
The number 9 becomes the next digit in our result. 
Result so far: 2699.0
Subtracting 5553 from 5933 leaves us with 380.
Take the next digit (9) from the dividend and append it to 380, then repeat: 3809 / 617

Step 8:
The number 617 fits into 3809 6 times, leaving a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 26996.0
Deduct 3702 from 3809 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 9:
617 goes into 1070 1 times with a remainder of 453.
Put 1 as the next digit of the answer. 
Result so far: 26996.1
If we take 617 away from 1070, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Step 10:
617 can be fit into 4530 7 times, resulting in a remainder of 211.
Write down 7 as next digit of the result. 
Result so far: 26996.17
Subtract 4319 from 4530 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 11:
When dividing 2110 by 617, we get 3 with a remainder of 259.
Use 3 as the next digit of our solution. 
Result so far: 26996.173
If we take 1851 away from 2110, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 12:
The number 617 fits into 2590 4 times, leaving a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 26996.1734
Deduct 2468 from 2590 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 13:
617 goes into 1220 1 times with a remainder of 603.
Put 1 as the next digit of the answer. 
Result so far: 26996.17341
If we subtract 617 from 1220, we get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

On to step 14:
The number 617 fits into 6030 9 times, leaving a remainder of 477.
The number 9 becomes the next digit in our result. 
Result so far: 26996.173419
Deduct 5553 from 6030 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 15:
617 goes into 4770 7 times with a remainder of 451.
Put 7 as the next digit of the answer. 
Result so far: 26996.1734197
Deduct 4319 from 4770 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 16:
617 goes into 4510 7 times with a remainder of 191.
The next digit of our result is 7. 
Result so far: 26996.17341977
If we subtract 4319 from 4510, 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.

Our division results in 26996.17341977 with a remaining 1.91e-07.
