63506844 ÷ 853 
The aim is to understand the frequency of 853 in 63506844.

Going ahead to step 1:
If we divide 6 by 853, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 853

On to step 2:
The number 853 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 853

Moving on to step 3:
853 goes into 635 0 times with a remainder of 635.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 635, we end up with 635.
Grab the next digit (0) from the dividend, add it to 635, then carry on: 6350 / 853

Let's proceed to step 4:
853 goes into 6350 7 times with a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 379 after subtracting 5971 from 6350.
Bring next digit (6) of the dividend behind the 379 and repeat the process: 3796 / 853

Advancing to step 5:
853 goes into 3796 4 times with a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 3412 from 3796 and we're left with 384.
Take the next digit (8) from the dividend and append it to 384, then repeat: 3848 / 853

On to step 6:
853 can be fit into 3848 4 times, resulting in a remainder of 436.
The next digit of our result is 4. 
Result so far: 744.0
The remainder is 436 after subtracting 3412 from 3848.
Fetch the next digit (4) from the dividend, attach it to 436 and continue: 4364 / 853

Going ahead to step 7:
When dividing 4364 by 853, we get 5 with a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 7445.0
If we subtract 4265 from 4364, we get 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 853

Going ahead to step 8:
853 goes into 994 1 times with a remainder of 141.
The next digit of our result is 1. 
Result so far: 74451.0
Deduct 853 from 994 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
The number 853 fits into 1410 1 times, leaving a remainder of 557.
The number 1 becomes the next digit in our result. 
Result so far: 74451.1
The remainder is 557 after subtracting 853 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Let's proceed to step 10:
5570 divided by 853 is 6 with a remainder of 452.
Use 6 as the next digit of our solution. 
Result so far: 74451.16
Deduct 5118 from 5570 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 11:
The number 853 fits into 4520 5 times, leaving a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 74451.165
Subtract 4265 from 4520 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 12:
2550 divided by 853 is 2 with a remainder of 844.
The next digit of our result is 2. 
Result so far: 74451.1652
Subtract 1706 from 2550 to get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

On to step 13:
8440 divided by 853 is 9 with a remainder of 763.
Write down 9 as next digit of the result. 
Result so far: 74451.16529
If we subtract 7677 from 8440, we get 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

On to step 14:
When dividing 7630 by 853, we get 8 with a remainder of 806.
The number 8 becomes the next digit in our result. 
Result so far: 74451.165298
Subtracting 6824 from 7630 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Moving on to step 15:
853 goes into 8060 9 times with a remainder of 383.
Put 9 as the next digit of the answer. 
Result so far: 74451.1652989
If we take 7677 away from 8060, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 16:
When dividing 3830 by 853, we get 4 with a remainder of 418.
The next digit of our result is 4. 
Result so far: 74451.16529894
If we take 3412 away from 3830, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

After the division, we end up with 74451.16529894 and a remainder of 4.18e-07.
