We divide 71878613 by 836
The aim is to understand the frequency of 836 in 71878613.

On to step 1:
836 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
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 836

Advancing to step 2:
71 divided by 836 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 836

Going ahead to step 3:
When dividing 718 by 836, we get 0 with a remainder of 718.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 718 and we're left with 718.
Bring next digit (7) of the dividend behind the 718 and repeat the process: 7187 / 836

Step 4:
836 can be fit into 7187 8 times, resulting in a remainder of 499.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6688 away from 7187, we end up with 499.
Include the next digit (8) from the dividend after 499, then repeat: 4998 / 836

Step 5:
When dividing 4998 by 836, we get 5 with a remainder of 818.
The next digit of our result is 5. 
Result so far: 85.0
The remainder is 818 after subtracting 4180 from 4998.
Include the next digit (6) from the dividend after 818, then repeat: 8186 / 836

Moving on to step 6:
8186 divided by 836 is 9 with a remainder of 662.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
The remainder is 662 after subtracting 7524 from 8186.
Append the next digit (1) from the dividend to 662 and continue with: 6621 / 836

Moving on to step 7:
The number 836 fits into 6621 7 times, leaving a remainder of 769.
Record the quotient 7 as the next digit in the result. 
Result so far: 8597.0
If we take 5852 away from 6621, we end up with 769.
Include the next digit (3) from the dividend after 769, then repeat: 7693 / 836

Going ahead to step 8:
The number 836 fits into 7693 9 times, leaving a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 85979.0
Deduct 7524 from 7693 and we're left 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.

Step 9:
When dividing 1690 by 836, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 85979.2
Subtract 1672 from 1690 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 836 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 85979.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
836 goes into 1800 2 times with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 85979.202
Subtract 1672 from 1800 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
If we divide 1280 by 836, we get 1 and a remainder of 444.
The number 1 becomes the next digit in our result. 
Result so far: 85979.2021
If we take 836 away from 1280, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 13:
The number 836 fits into 4440 5 times, leaving a remainder of 260.
The next digit of our result is 5. 
Result so far: 85979.20215
If we take 4180 away from 4440, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
If we divide 2600 by 836, we get 3 and a remainder of 92.
The next digit of our result is 3. 
Result so far: 85979.202153
Subtract 2508 from 2600 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 15:
836 goes into 920 1 times with a remainder of 84.
The number 1 becomes the next digit in our result. 
Result so far: 85979.2021531
The remainder is 84 after subtracting 836 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 16:
836 can be fit into 840 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 85979.20215311
Subtracting 836 from 840 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 85979.20215311 with a balance of 4e-09.
