371891 ÷ 58 
The aim is to understand the frequency of 58 in 371891.

On to step 1:
58 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
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 58

Step 2:
When dividing 37 by 58, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 58

Step 3:
58 goes into 371 6 times with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 348 from 371 and we're left with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 58

Moving on to step 4:
58 can be fit into 238 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 232 from 238 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 58

Step 5:
The number 58 fits into 69 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 641.0
Deduct 58 from 69 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 58

Going ahead to step 6:
58 goes into 111 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 6411.0
If we take 58 away from 111, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
58 can be fit into 530 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 6411.9
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
The number 58 fits into 80 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 6411.91
Subtract 58 from 80 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
The number 58 fits into 220 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 6411.913
Subtracting 174 from 220 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
58 goes into 460 7 times with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 6411.9137
If we take 406 away from 460, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
58 can be fit into 540 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 6411.91379
If we subtract 522 from 540, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
If we divide 180 by 58, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 6411.913793
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
When dividing 60 by 58, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 6411.9137931
Deduct 58 from 60 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
When dividing 20 by 58, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6411.9137931
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 6411.9137931 with a remainder of 2e-08.
