Let's divide 35671570 by 591
The aim is to understand the frequency of 591 in 35671570.

Step 1:
591 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 591

Going ahead to step 2:
35 divided by 591 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 591

Advancing to step 3:
356 divided by 591 is 0 with a remainder of 356.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 356, we get 356.
Append the next digit (7) from the dividend to 356 and continue with: 3567 / 591

Advancing to step 4:
When dividing 3567 by 591, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3546 from 3567 and we're left with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 591

Going ahead to step 5:
211 divided by 591 is 0 with a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtract 0 from 211 to get 211.
Bring next digit (5) of the dividend behind the 211 and repeat the process: 2115 / 591

Let's proceed to step 6:
When dividing 2115 by 591, we get 3 with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 603.0
If we subtract 1773 from 2115, we get 342.
Bring next digit (7) of the dividend behind the 342 and repeat the process: 3427 / 591

Moving on to step 7:
591 goes into 3427 5 times with a remainder of 472.
Put 5 as the next digit of the answer. 
Result so far: 6035.0
Subtract 2955 from 3427 to get 472.
Fetch the next digit (0) from the dividend, attach it to 472 and continue: 4720 / 591

Step 8:
When dividing 4720 by 591, we get 7 with a remainder of 583.
Record the quotient 7 as the next digit in the result. 
Result so far: 60357.0
Subtracting 4137 from 4720 leaves us with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Let's proceed to step 9:
591 goes into 5830 9 times with a remainder of 511.
Write down 9 as next digit of the result. 
Result so far: 60357.9
Subtract 5319 from 5830 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 10:
The number 591 fits into 5110 8 times, leaving a remainder of 382.
Record the quotient 8 as the next digit in the result. 
Result so far: 60357.98
If we take 4728 away from 5110, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 11:
3820 divided by 591 is 6 with a remainder of 274.
The next digit of our result is 6. 
Result so far: 60357.986
Subtract 3546 from 3820 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 12:
591 goes into 2740 4 times with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 60357.9864
If we take 2364 away from 2740, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 13:
The number 591 fits into 3760 6 times, leaving a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 60357.98646
Deduct 3546 from 3760 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 14:
When dividing 2140 by 591, we get 3 with a remainder of 367.
Write down 3 as next digit of the result. 
Result so far: 60357.986463
Deduct 1773 from 2140 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 15:
591 can be fit into 3670 6 times, resulting in a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 60357.9864636
Subtract 3546 from 3670 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 16:
1240 divided by 591 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 60357.98646362
If we take 1182 away from 1240, 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.

The final outcome is 60357.98646362, with a leftover of 5.8e-08.
