We look at the division of 3907071 by 685 
The aim is to understand the frequency of 685 in 3907071.

On to step 1:
685 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 685

Step 2:
39 divided by 685 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 685

Moving on to step 3:
685 goes into 390 0 times with a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 390 after subtracting 0 from 390.
Bring next digit (7) of the dividend behind the 390 and repeat the process: 3907 / 685

On to step 4:
The number 685 fits into 3907 5 times, leaving a remainder of 482.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 482 after subtracting 3425 from 3907.
Fetch the next digit (0) from the dividend, attach it to 482 and continue: 4820 / 685

On to step 5:
When dividing 4820 by 685, we get 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 4795 away from 4820, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 685

Going ahead to step 6:
685 can be fit into 257 0 times, resulting in a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 570.0
If we take 0 away from 257, we end up with 257.
Fetch the next digit (1) from the dividend, attach it to 257 and continue: 2571 / 685

On to step 7:
When dividing 2571 by 685, we get 3 with a remainder of 516.
The number 3 becomes the next digit in our result. 
Result so far: 5703.0
Subtract 2055 from 2571 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 8:
685 goes into 5160 7 times with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 5703.7
If we take 4795 away from 5160, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
685 goes into 3650 5 times with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 5703.75
The remainder is 225 after subtracting 3425 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
The number 685 fits into 2250 3 times, leaving a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 5703.753
Subtracting 2055 from 2250 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 11:
1950 divided by 685 is 2 with a remainder of 580.
Put 2 as the next digit of the answer. 
Result so far: 5703.7532
Deduct 1370 from 1950 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 12:
685 goes into 5800 8 times with a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 5703.75328
If we take 5480 away from 5800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
The number 685 fits into 3200 4 times, leaving a remainder of 460.
Use 4 as the next digit of our solution. 
Result so far: 5703.753284
If we take 2740 away from 3200, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 14:
The number 685 fits into 4600 6 times, leaving a remainder of 490.
Put 6 as the next digit of the answer. 
Result so far: 5703.7532846
Subtract 4110 from 4600 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 15:
If we divide 4900 by 685, we get 7 and a remainder of 105.
Write down 7 as next digit of the result. 
Result so far: 5703.75328467
The remainder is 105 after subtracting 4795 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 5703.75328467 with a balance of 1.05e-07.
