7071949 ÷ 391 
The aim is to understand the frequency of 391 in 7071949.

Moving on to step 1:
391 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 391

On to step 2:
If we divide 70 by 391, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 391

On to step 3:
When dividing 707 by 391, we get 1 with a remainder of 316.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 391 from 707 to get 316.
Fetch the next digit (1) from the dividend, attach it to 316 and continue: 3161 / 391

Going ahead to step 4:
3161 divided by 391 is 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 3128 away from 3161, we end up with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 391

Let's proceed to step 5:
If we divide 339 by 391, we get 0 and a remainder of 339.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Deduct 0 from 339 and we're left with 339.
Take the next digit (4) from the dividend and append it to 339, then repeat: 3394 / 391

Step 6:
391 goes into 3394 8 times with a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 1808.0
Subtract 3128 from 3394 to get 266.
Bring next digit (9) of the dividend behind the 266 and repeat the process: 2669 / 391

Advancing to step 7:
If we divide 2669 by 391, we get 6 and a remainder of 323.
Put 6 as the next digit of the answer. 
Result so far: 18086.0
If we take 2346 away from 2669, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 8:
If we divide 3230 by 391, we get 8 and a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 18086.8
Deduct 3128 from 3230 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 9:
When dividing 1020 by 391, we get 2 with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 18086.82
Subtract 782 from 1020 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 10:
391 can be fit into 2380 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 18086.826
Deduct 2346 from 2380 and we're left with 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 11:
340 divided by 391 is 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 18086.826
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
391 goes into 3400 8 times with a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 18086.82608
Deduct 3128 from 3400 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 13:
If we divide 2720 by 391, we get 6 and a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 18086.826086
Deduct 2346 from 2720 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 14:
391 can be fit into 3740 9 times, resulting in a remainder of 221.
The next digit of our result is 9. 
Result so far: 18086.8260869
If we subtract 3519 from 3740, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 15:
The number 391 fits into 2210 5 times, leaving a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 18086.82608695
The remainder is 255 after subtracting 1955 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Our division results in 18086.82608695 with a remaining 2.55e-07.
