5725468 ÷ 686 
The aim is to understand the frequency of 686 in 5725468.

Let's proceed to step 1:
If we divide 5 by 686, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 686

On to step 2:
686 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 686

Going ahead to step 3:
If we divide 572 by 686, we get 0 and a remainder of 572.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 572 to get 572.
Include the next digit (5) from the dividend after 572, then repeat: 5725 / 686

Step 4:
686 can be fit into 5725 8 times, resulting in a remainder of 237.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5488 from 5725, we get 237.
Fetch the next digit (4) from the dividend, attach it to 237 and continue: 2374 / 686

Step 5:
686 can be fit into 2374 3 times, resulting in a remainder of 316.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Deduct 2058 from 2374 and we're left with 316.
Fetch the next digit (6) from the dividend, attach it to 316 and continue: 3166 / 686

Going ahead to step 6:
If we divide 3166 by 686, we get 4 and a remainder of 422.
Put 4 as the next digit of the answer. 
Result so far: 834.0
Deduct 2744 from 3166 and we're left with 422.
Append the next digit (8) from the dividend to 422 and continue with: 4228 / 686

Let's proceed to step 7:
686 can be fit into 4228 6 times, resulting in a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 8346.0
Subtracting 4116 from 4228 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 8:
The number 686 fits into 1120 1 times, leaving a remainder of 434.
Put 1 as the next digit of the answer. 
Result so far: 8346.1
If we subtract 686 from 1120, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 9:
686 can be fit into 4340 6 times, resulting in a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 8346.16
If we take 4116 away from 4340, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
The number 686 fits into 2240 3 times, leaving a remainder of 182.
Use 3 as the next digit of our solution. 
Result so far: 8346.163
Subtracting 2058 from 2240 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 11:
686 goes into 1820 2 times with a remainder of 448.
Record the quotient 2 as the next digit in the result. 
Result so far: 8346.1632
Deduct 1372 from 1820 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 12:
When dividing 4480 by 686, we get 6 with a remainder of 364.
The next digit of our result is 6. 
Result so far: 8346.16326
If we subtract 4116 from 4480, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 13:
If we divide 3640 by 686, we get 5 and a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 8346.163265
If we take 3430 away from 3640, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 14:
If we divide 2100 by 686, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 8346.1632653
If we subtract 2058 from 2100, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
If we divide 420 by 686, we get 0 and a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 8346.1632653
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 8346.1632653, and the remainder is 4.2e-07.
