We divide 70445967 by 391
The aim is to understand the frequency of 391 in 70445967.

Going ahead to step 1:
7 divided by 391 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 391

Advancing to step 2:
The number 391 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 391

Going ahead to step 3:
391 can be fit into 704 1 times, resulting in a remainder of 313.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 391 from 704 and we're left with 313.
Include the next digit (4) from the dividend after 313, then repeat: 3134 / 391

Going ahead to step 4:
When dividing 3134 by 391, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 6 after subtracting 3128 from 3134.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 391

Going ahead to step 5:
391 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 391

Moving on to step 6:
The number 391 fits into 659 1 times, leaving a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 1801.0
The remainder is 268 after subtracting 391 from 659.
Include the next digit (6) from the dividend after 268, then repeat: 2686 / 391

Step 7:
When dividing 2686 by 391, we get 6 with a remainder of 340.
The number 6 becomes the next digit in our result. 
Result so far: 18016.0
If we take 2346 away from 2686, we end up with 340.
Take the next digit (7) from the dividend and append it to 340, then repeat: 3407 / 391

Let's proceed to step 8:
If we divide 3407 by 391, we get 8 and a remainder of 279.
Put 8 as the next digit of the answer. 
Result so far: 180168.0
If we subtract 3128 from 3407, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 9:
When dividing 2790 by 391, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 180168.7
The remainder is 53 after subtracting 2737 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 10:
If we divide 530 by 391, we get 1 and a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 180168.71
Subtracting 391 from 530 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 11:
When dividing 1390 by 391, we get 3 with a remainder of 217.
Write down 3 as next digit of the result. 
Result so far: 180168.713
Deduct 1173 from 1390 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 12:
391 goes into 2170 5 times with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 180168.7135
Subtracting 1955 from 2170 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
When dividing 2150 by 391, we get 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 180168.71355
Subtract 1955 from 2150 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The quotient of the division is 180168.71355, and the remainder is 0.000195.
