We look at the division of 57771948 by 838 
The aim is to understand the frequency of 838 in 57771948.

Step 1:
5 divided by 838 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 838

Moving on to step 2:
If we divide 57 by 838, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 838

Let's proceed to step 3:
The number 838 fits into 577 0 times, leaving a remainder of 577.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 577, we end up with 577.
Include the next digit (7) from the dividend after 577, then repeat: 5777 / 838

On to step 4:
The number 838 fits into 5777 6 times, leaving a remainder of 749.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 5028 from 5777 and we're left with 749.
Bring next digit (1) of the dividend behind the 749 and repeat the process: 7491 / 838

Advancing to step 5:
7491 divided by 838 is 8 with a remainder of 787.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtracting 6704 from 7491 leaves us with 787.
Fetch the next digit (9) from the dividend, attach it to 787 and continue: 7879 / 838

Moving on to step 6:
When dividing 7879 by 838, we get 9 with a remainder of 337.
Write down 9 as next digit of the result. 
Result so far: 689.0
The remainder is 337 after subtracting 7542 from 7879.
Append the next digit (4) from the dividend to 337 and continue with: 3374 / 838

Advancing to step 7:
3374 divided by 838 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 6894.0
If we take 3352 away from 3374, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 838

Advancing to step 8:
If we divide 228 by 838, we get 0 and a remainder of 228.
The number 0 becomes the next digit in our result. 
Result so far: 68940.0
Deduct 0 from 228 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 9:
838 can be fit into 2280 2 times, resulting in a remainder of 604.
Put 2 as the next digit of the answer. 
Result so far: 68940.2
Deduct 1676 from 2280 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 10:
If we divide 6040 by 838, we get 7 and a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 68940.27
If we take 5866 away from 6040, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
838 can be fit into 1740 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 68940.272
Subtracting 1676 from 1740 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
640 divided by 838 is 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 68940.272
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
838 can be fit into 6400 7 times, resulting in a remainder of 534.
The number 7 becomes the next digit in our result. 
Result so far: 68940.27207
If we take 5866 away from 6400, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 14:
The number 838 fits into 5340 6 times, leaving a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 68940.272076
Subtracting 5028 from 5340 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 15:
3120 divided by 838 is 3 with a remainder of 606.
Write down 3 as next digit of the result. 
Result so far: 68940.2720763
Deduct 2514 from 3120 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 16:
838 can be fit into 6060 7 times, resulting in a remainder of 194.
Use 7 as the next digit of our solution. 
Result so far: 68940.27207637
Deduct 5866 from 6060 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

In conclusion, the division gives 68940.27207637 with a balance of 1.94e-07.
