We're dividing 57321516 by 813 
The aim is to understand the frequency of 813 in 57321516.

Let's proceed to step 1:
If we divide 5 by 813, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 813

Step 2:
813 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 813

Going ahead to step 3:
When dividing 573 by 813, we get 0 with a remainder of 573.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 573, we end up with 573.
Bring next digit (2) of the dividend behind the 573 and repeat the process: 5732 / 813

Step 4:
813 goes into 5732 7 times with a remainder of 41.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 41 after subtracting 5691 from 5732.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 813

On to step 5:
813 can be fit into 411 0 times, resulting in a remainder of 411.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 411 and we're left with 411.
Append the next digit (5) from the dividend to 411 and continue with: 4115 / 813

Let's proceed to step 6:
The number 813 fits into 4115 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 705.0
If we subtract 4065 from 4115, we get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 813

Step 7:
The number 813 fits into 501 0 times, leaving a remainder of 501.
Record the quotient 0 as the next digit in the result. 
Result so far: 7050.0
Subtracting 0 from 501 leaves us with 501.
Bring next digit (6) of the dividend behind the 501 and repeat the process: 5016 / 813

Step 8:
813 can be fit into 5016 6 times, resulting in a remainder of 138.
The next digit of our result is 6. 
Result so far: 70506.0
The remainder is 138 after subtracting 4878 from 5016.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
If we divide 1380 by 813, we get 1 and a remainder of 567.
The next digit of our result is 1. 
Result so far: 70506.1
Subtracting 813 from 1380 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 10:
If we divide 5670 by 813, we get 6 and a remainder of 792.
Put 6 as the next digit of the answer. 
Result so far: 70506.16
Subtract 4878 from 5670 to get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 11:
If we divide 7920 by 813, we get 9 and a remainder of 603.
Write down 9 as next digit of the result. 
Result so far: 70506.169
Subtract 7317 from 7920 to get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Step 12:
If we divide 6030 by 813, we get 7 and a remainder of 339.
Write down 7 as next digit of the result. 
Result so far: 70506.1697
The remainder is 339 after subtracting 5691 from 6030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 13:
If we divide 3390 by 813, we get 4 and a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 70506.16974
If we subtract 3252 from 3390, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 14:
The number 813 fits into 1380 1 times, leaving a remainder of 567.
Write down 1 as next digit of the result. 
Result so far: 70506.169741
If we subtract 813 from 1380, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Let's proceed to step 15:
813 goes into 5670 6 times with a remainder of 792.
The number 6 becomes the next digit in our result. 
Result so far: 70506.1697416
The remainder is 792 after subtracting 4878 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Step 16:
If we divide 7920 by 813, we get 9 and a remainder of 603.
Write down 9 as next digit of the result. 
Result so far: 70506.16974169
The remainder is 603 after subtracting 7317 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

The quotient of the division is 70506.16974169, and the remainder is 6.03e-07.
