We're dividing 57810714 by 393 
The aim is to understand the frequency of 393 in 57810714.

Advancing to step 1:
393 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 393

Step 2:
When dividing 57 by 393, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 393

Moving on to step 3:
393 can be fit into 578 1 times, resulting in a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 393 from 578 to get 185.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 393

On to step 4:
393 goes into 1851 4 times with a remainder of 279.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 1572 away from 1851, we end up with 279.
Grab the next digit (0) from the dividend, add it to 279, then carry on: 2790 / 393

Moving on to step 5:
2790 divided by 393 is 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we subtract 2751 from 2790, we get 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 393

Going ahead to step 6:
397 divided by 393 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1471.0
Subtract 393 from 397 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 393

Moving on to step 7:
41 divided by 393 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 14710.0
If we subtract 0 from 41, we get 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 393

Step 8:
When dividing 414 by 393, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 147101.0
Deduct 393 from 414 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
The number 393 fits into 210 0 times, leaving a remainder of 210.
The next digit of our result is 0. 
Result so far: 147101.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
393 can be fit into 2100 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 147101.05
If we take 1965 away from 2100, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
If we divide 1350 by 393, we get 3 and a remainder of 171.
Use 3 as the next digit of our solution. 
Result so far: 147101.053
If we subtract 1179 from 1350, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 12:
1710 divided by 393 is 4 with a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 147101.0534
Deduct 1572 from 1710 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 13:
If we divide 1380 by 393, we get 3 and a remainder of 201.
Put 3 as the next digit of the answer. 
Result so far: 147101.05343
Deduct 1179 from 1380 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 14:
393 can be fit into 2010 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 147101.053435
If we subtract 1965 from 2010, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 15:
If we divide 450 by 393, we get 1 and a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 147101.0534351
If we take 393 away from 450, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 16:
393 can be fit into 570 1 times, resulting in a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 147101.05343511
If we take 393 away from 570, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

After the division, we end up with 147101.05343511 and a remainder of 1.77e-07.
