73525820 divided by 686 
The aim is to understand the frequency of 686 in 73525820.

Step 1:
686 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 686

Step 2:
When dividing 73 by 686, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 686

Step 3:
When dividing 735 by 686, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
If we take 686 away from 735, we end up with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 686

Advancing to step 4:
492 divided by 686 is 0 with a remainder of 492.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 492 after subtracting 0 from 492.
Include the next digit (5) from the dividend after 492, then repeat: 4925 / 686

Let's proceed to step 5:
When dividing 4925 by 686, we get 7 with a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 107.0
The remainder is 123 after subtracting 4802 from 4925.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 686

Let's proceed to step 6:
686 goes into 1238 1 times with a remainder of 552.
The number 1 becomes the next digit in our result. 
Result so far: 1071.0
Deduct 686 from 1238 and we're left with 552.
Fetch the next digit (2) from the dividend, attach it to 552 and continue: 5522 / 686

Moving on to step 7:
When dividing 5522 by 686, we get 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 10718.0
If we take 5488 away from 5522, we end up with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 686

Moving on to step 8:
686 goes into 340 0 times with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 107180.0
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
3400 divided by 686 is 4 with a remainder of 656.
Use 4 as the next digit of our solution. 
Result so far: 107180.4
Subtracting 2744 from 3400 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 10:
686 can be fit into 6560 9 times, resulting in a remainder of 386.
Put 9 as the next digit of the answer. 
Result so far: 107180.49
The remainder is 386 after subtracting 6174 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 11:
The number 686 fits into 3860 5 times, leaving a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 107180.495
Deduct 3430 from 3860 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 12:
When dividing 4300 by 686, we get 6 with a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 107180.4956
The remainder is 184 after subtracting 4116 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 13:
686 can be fit into 1840 2 times, resulting in a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 107180.49562
Deduct 1372 from 1840 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 14:
The number 686 fits into 4680 6 times, leaving a remainder of 564.
Record the quotient 6 as the next digit in the result. 
Result so far: 107180.495626
The remainder is 564 after subtracting 4116 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 15:
When dividing 5640 by 686, we get 8 with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 107180.4956268
If we subtract 5488 from 5640, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 16:
1520 divided by 686 is 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 107180.49562682
Subtract 1372 from 1520 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Our division results in 107180.49562682 with a remaining 1.48e-07.
