We look at the division of 35597730 by 686 
The aim is to understand the frequency of 686 in 35597730.

Let's proceed to step 1:
3 divided by 686 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 686

Let's proceed to step 2:
35 divided by 686 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 686

Let's proceed to step 3:
686 goes into 355 0 times with a remainder of 355.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 355 to get 355.
Bring next digit (9) of the dividend behind the 355 and repeat the process: 3559 / 686

Going ahead to step 4:
686 goes into 3559 5 times with a remainder of 129.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3430 from 3559 to get 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 686

Advancing to step 5:
1297 divided by 686 is 1 with a remainder of 611.
The next digit of our result is 1. 
Result so far: 51.0
The remainder is 611 after subtracting 686 from 1297.
Bring next digit (7) of the dividend behind the 611 and repeat the process: 6117 / 686

Let's proceed to step 6:
If we divide 6117 by 686, we get 8 and a remainder of 629.
Put 8 as the next digit of the answer. 
Result so far: 518.0
Subtracting 5488 from 6117 leaves us with 629.
Append the next digit (3) from the dividend to 629 and continue with: 6293 / 686

Moving on to step 7:
If we divide 6293 by 686, we get 9 and a remainder of 119.
Use 9 as the next digit of our solution. 
Result so far: 5189.0
If we take 6174 away from 6293, we end up with 119.
Grab the next digit (0) from the dividend, add it to 119, then carry on: 1190 / 686

Advancing to step 8:
686 can be fit into 1190 1 times, resulting in a remainder of 504.
Record the quotient 1 as the next digit in the result. 
Result so far: 51891.0
Deduct 686 from 1190 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 9:
686 goes into 5040 7 times with a remainder of 238.
Put 7 as the next digit of the answer. 
Result so far: 51891.7
Deduct 4802 from 5040 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 10:
2380 divided by 686 is 3 with a remainder of 322.
The next digit of our result is 3. 
Result so far: 51891.73
Subtract 2058 from 2380 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 11:
686 can be fit into 3220 4 times, resulting in a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 51891.734
The remainder is 476 after subtracting 2744 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 12:
The number 686 fits into 4760 6 times, leaving a remainder of 644.
Put 6 as the next digit of the answer. 
Result so far: 51891.7346
If we subtract 4116 from 4760, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 13:
686 goes into 6440 9 times with a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 51891.73469
The remainder is 266 after subtracting 6174 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 14:
If we divide 2660 by 686, we get 3 and a remainder of 602.
Put 3 as the next digit of the answer. 
Result so far: 51891.734693
Subtract 2058 from 2660 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 15:
If we divide 6020 by 686, we get 8 and a remainder of 532.
Record the quotient 8 as the next digit in the result. 
Result so far: 51891.7346938
Subtracting 5488 from 6020 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 16:
686 goes into 5320 7 times with a remainder of 518.
Put 7 as the next digit of the answer. 
Result so far: 51891.73469387
The remainder is 518 after subtracting 4802 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

The final result is 51891.73469387 with a remainder of 5.18e-07.
