57907141 ÷ 394 
The aim is to understand the frequency of 394 in 57907141.

Moving on to step 1:
The number 394 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 394

Moving on to step 2:
57 divided by 394 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 394

Let's proceed to step 3:
The number 394 fits into 579 1 times, leaving a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 185 after subtracting 394 from 579.
Include the next digit (0) from the dividend after 185, then repeat: 1850 / 394

Let's proceed to step 4:
394 goes into 1850 4 times with a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1576 from 1850 and we're left with 274.
Include the next digit (7) from the dividend after 274, then repeat: 2747 / 394

Going ahead to step 5:
If we divide 2747 by 394, we get 6 and a remainder of 383.
The next digit of our result is 6. 
Result so far: 146.0
Subtract 2364 from 2747 to get 383.
Include the next digit (1) from the dividend after 383, then repeat: 3831 / 394

Going ahead to step 6:
When dividing 3831 by 394, we get 9 with a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 1469.0
If we subtract 3546 from 3831, we get 285.
Grab the next digit (4) from the dividend, add it to 285, then carry on: 2854 / 394

Moving on to step 7:
394 goes into 2854 7 times with a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 14697.0
If we take 2758 away from 2854, we end up with 96.
Include the next digit (1) from the dividend after 96, then repeat: 961 / 394

Going ahead to step 8:
961 divided by 394 is 2 with a remainder of 173.
Record the quotient 2 as the next digit in the result. 
Result so far: 146972.0
Subtracting 788 from 961 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 9:
The number 394 fits into 1730 4 times, leaving a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 146972.4
If we subtract 1576 from 1730, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
394 can be fit into 1540 3 times, resulting in a remainder of 358.
Put 3 as the next digit of the answer. 
Result so far: 146972.43
Subtract 1182 from 1540 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 11:
394 can be fit into 3580 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 146972.439
If we subtract 3546 from 3580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
340 divided by 394 is 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 146972.439
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 13:
394 goes into 3400 8 times with a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 146972.43908
Subtracting 3152 from 3400 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
If we divide 2480 by 394, we get 6 and a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 146972.439086
If we subtract 2364 from 2480, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 15:
The number 394 fits into 1160 2 times, leaving a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 146972.4390862
The remainder is 372 after subtracting 788 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 16:
394 goes into 3720 9 times with a remainder of 174.
Use 9 as the next digit of our solution. 
Result so far: 146972.43908629
The remainder is 174 after subtracting 3546 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The quotient of the division is 146972.43908629, and the remainder is 1.74e-07.
