We divide 81259853 by 828
The aim is to understand the frequency of 828 in 81259853.

Going ahead to step 1:
When dividing 8 by 828, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 828

Advancing to step 2:
When dividing 81 by 828, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 828

Let's proceed to step 3:
828 goes into 812 0 times with a remainder of 812.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 812 leaves us with 812.
Bring next digit (5) of the dividend behind the 812 and repeat the process: 8125 / 828

On to step 4:
If we divide 8125 by 828, we get 9 and a remainder of 673.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7452 away from 8125, we end up with 673.
Append the next digit (9) from the dividend to 673 and continue with: 6739 / 828

Going ahead to step 5:
When dividing 6739 by 828, we get 8 with a remainder of 115.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 6624 from 6739 and we're left with 115.
Grab the next digit (8) from the dividend, add it to 115, then carry on: 1158 / 828

On to step 6:
When dividing 1158 by 828, we get 1 with a remainder of 330.
The number 1 becomes the next digit in our result. 
Result so far: 981.0
Subtracting 828 from 1158 leaves us with 330.
Include the next digit (5) from the dividend after 330, then repeat: 3305 / 828

Going ahead to step 7:
3305 divided by 828 is 3 with a remainder of 821.
Record the quotient 3 as the next digit in the result. 
Result so far: 9813.0
If we take 2484 away from 3305, we end up with 821.
Append the next digit (3) from the dividend to 821 and continue with: 8213 / 828

Step 8:
8213 divided by 828 is 9 with a remainder of 761.
Use 9 as the next digit of our solution. 
Result so far: 98139.0
Deduct 7452 from 8213 and we're left with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Advancing to step 9:
If we divide 7610 by 828, we get 9 and a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 98139.9
If we take 7452 away from 7610, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
The number 828 fits into 1580 1 times, leaving a remainder of 752.
Record the quotient 1 as the next digit in the result. 
Result so far: 98139.91
Subtract 828 from 1580 to get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Step 11:
828 goes into 7520 9 times with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 98139.919
Subtracting 7452 from 7520 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
828 can be fit into 680 0 times, resulting in a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 98139.919
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 13:
828 can be fit into 6800 8 times, resulting in a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 98139.91908
Deduct 6624 from 6800 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
828 can be fit into 1760 2 times, resulting in a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 98139.919082
The remainder is 104 after subtracting 1656 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 15:
828 goes into 1040 1 times with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 98139.9190821
Subtracting 828 from 1040 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 16:
828 goes into 2120 2 times with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 98139.91908212
Deduct 1656 from 2120 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

In conclusion, the division gives 98139.91908212 with a balance of 4.64e-07.
