60385342 divided by 391 
The aim is to understand the frequency of 391 in 60385342.

Let's proceed to step 1:
When dividing 6 by 391, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 391

On to step 2:
391 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 391

Advancing to step 3:
When dividing 603 by 391, we get 1 with a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 391 from 603, we get 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 391

Step 4:
391 goes into 2128 5 times with a remainder of 173.
The next digit of our result is 5. 
Result so far: 15.0
If we take 1955 away from 2128, we end up with 173.
Fetch the next digit (5) from the dividend, attach it to 173 and continue: 1735 / 391

Advancing to step 5:
391 goes into 1735 4 times with a remainder of 171.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtracting 1564 from 1735 leaves us with 171.
Take the next digit (3) from the dividend and append it to 171, then repeat: 1713 / 391

Step 6:
1713 divided by 391 is 4 with a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 1544.0
The remainder is 149 after subtracting 1564 from 1713.
Append the next digit (4) from the dividend to 149 and continue with: 1494 / 391

Let's proceed to step 7:
When dividing 1494 by 391, we get 3 with a remainder of 321.
Record the quotient 3 as the next digit in the result. 
Result so far: 15443.0
If we subtract 1173 from 1494, we get 321.
Grab the next digit (2) from the dividend, add it to 321, then carry on: 3212 / 391

Step 8:
391 goes into 3212 8 times with a remainder of 84.
The next digit of our result is 8. 
Result so far: 154438.0
If we subtract 3128 from 3212, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
If we divide 840 by 391, we get 2 and a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 154438.2
If we take 782 away from 840, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
391 goes into 580 1 times with a remainder of 189.
Write down 1 as next digit of the result. 
Result so far: 154438.21
If we subtract 391 from 580, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 11:
When dividing 1890 by 391, we get 4 with a remainder of 326.
Write down 4 as next digit of the result. 
Result so far: 154438.214
If we subtract 1564 from 1890, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 12:
391 can be fit into 3260 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 154438.2148
Deduct 3128 from 3260 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 13:
The number 391 fits into 1320 3 times, leaving a remainder of 147.
The next digit of our result is 3. 
Result so far: 154438.21483
If we take 1173 away from 1320, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 14:
When dividing 1470 by 391, we get 3 with a remainder of 297.
Record the quotient 3 as the next digit in the result. 
Result so far: 154438.214833
Subtracting 1173 from 1470 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The quotient of the division is 154438.214833, and the remainder is 2.97e-05.
