10538267 divided by 686 
The aim is to understand the frequency of 686 in 10538267.

Going ahead to step 1:
686 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 686

Going ahead to step 2:
When dividing 10 by 686, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 686

Step 3:
686 can be fit into 105 0 times, resulting in a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 105 to get 105.
Fetch the next digit (3) from the dividend, attach it to 105 and continue: 1053 / 686

Moving on to step 4:
686 can be fit into 1053 1 times, resulting in a remainder of 367.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 367 after subtracting 686 from 1053.
Append the next digit (8) from the dividend to 367 and continue with: 3678 / 686

Going ahead to step 5:
The number 686 fits into 3678 5 times, leaving a remainder of 248.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 3430 from 3678 leaves us with 248.
Bring next digit (2) of the dividend behind the 248 and repeat the process: 2482 / 686

Advancing to step 6:
When dividing 2482 by 686, we get 3 with a remainder of 424.
Use 3 as the next digit of our solution. 
Result so far: 153.0
If we subtract 2058 from 2482, we get 424.
Grab the next digit (6) from the dividend, add it to 424, then carry on: 4246 / 686

Advancing to step 7:
When dividing 4246 by 686, we get 6 with a remainder of 130.
The number 6 becomes the next digit in our result. 
Result so far: 1536.0
Deduct 4116 from 4246 and we're left with 130.
Bring next digit (7) of the dividend behind the 130 and repeat the process: 1307 / 686

Going ahead to step 8:
When dividing 1307 by 686, we get 1 with a remainder of 621.
The next digit of our result is 1. 
Result so far: 15361.0
Deduct 686 from 1307 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Step 9:
When dividing 6210 by 686, we get 9 with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 15361.9
If we subtract 6174 from 6210, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
686 goes into 360 0 times with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 15361.9
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
686 goes into 3600 5 times with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 15361.905
Subtract 3430 from 3600 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
1700 divided by 686 is 2 with a remainder of 328.
The next digit of our result is 2. 
Result so far: 15361.9052
Deduct 1372 from 1700 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 13:
The number 686 fits into 3280 4 times, leaving a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 15361.90524
Deduct 2744 from 3280 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 14:
5360 divided by 686 is 7 with a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 15361.905247
Deduct 4802 from 5360 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 15:
If we divide 5580 by 686, we get 8 and a remainder of 92.
The next digit of our result is 8. 
Result so far: 15361.9052478
Subtract 5488 from 5580 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 16:
920 divided by 686 is 1 with a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 15361.90524781
If we subtract 686 from 920, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The quotient of the division is 15361.90524781, and the remainder is 2.34e-07.
