13256234 divided by 853 
The aim is to understand the frequency of 853 in 13256234.

On to step 1:
When dividing 1 by 853, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 853

Let's proceed to step 2:
853 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 853

On to step 3:
132 divided by 853 is 0 with a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 132 after subtracting 0 from 132.
Fetch the next digit (5) from the dividend, attach it to 132 and continue: 1325 / 853

Step 4:
1325 divided by 853 is 1 with a remainder of 472.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 853 from 1325 to get 472.
Append the next digit (6) from the dividend to 472 and continue with: 4726 / 853

Going ahead to step 5:
The number 853 fits into 4726 5 times, leaving a remainder of 461.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 4265 from 4726, we get 461.
Bring next digit (2) of the dividend behind the 461 and repeat the process: 4612 / 853

Advancing to step 6:
853 goes into 4612 5 times with a remainder of 347.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtracting 4265 from 4612 leaves us with 347.
Take the next digit (3) from the dividend and append it to 347, then repeat: 3473 / 853

On to step 7:
3473 divided by 853 is 4 with a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 1554.0
Deduct 3412 from 3473 and we're left with 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 853

Let's proceed to step 8:
614 divided by 853 is 0 with a remainder of 614.
The next digit of our result is 0. 
Result so far: 15540.0
If we take 0 away from 614, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 9:
The number 853 fits into 6140 7 times, leaving a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 15540.7
Subtracting 5971 from 6140 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 10:
If we divide 1690 by 853, we get 1 and a remainder of 837.
The next digit of our result is 1. 
Result so far: 15540.71
Subtract 853 from 1690 to get 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Moving on to step 11:
The number 853 fits into 8370 9 times, leaving a remainder of 693.
The number 9 becomes the next digit in our result. 
Result so far: 15540.719
If we subtract 7677 from 8370, we get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Step 12:
853 goes into 6930 8 times with a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 15540.7198
Deduct 6824 from 6930 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 13:
853 goes into 1060 1 times with a remainder of 207.
The next digit of our result is 1. 
Result so far: 15540.71981
If we take 853 away from 1060, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 14:
When dividing 2070 by 853, we get 2 with a remainder of 364.
Put 2 as the next digit of the answer. 
Result so far: 15540.719812
Deduct 1706 from 2070 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 15:
The number 853 fits into 3640 4 times, leaving a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 15540.7198124
If we subtract 3412 from 3640, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 16:
When dividing 2280 by 853, we get 2 with a remainder of 574.
The next digit of our result is 2. 
Result so far: 15540.71981242
If we subtract 1706 from 2280, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

The quotient of the division is 15540.71981242, and the remainder is 5.74e-07.
