Let's divide 58515787 by 145
The aim is to understand the frequency of 145 in 58515787.

Step 1:
The number 145 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 145

Let's proceed to step 2:
When dividing 58 by 145, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 145

Moving on to step 3:
When dividing 585 by 145, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 580 from 585 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 145

Going ahead to step 4:
145 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 145

On to step 5:
When dividing 515 by 145, we get 3 with a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 403.0
The remainder is 80 after subtracting 435 from 515.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 145

Let's proceed to step 6:
145 goes into 807 5 times with a remainder of 82.
Use 5 as the next digit of our solution. 
Result so far: 4035.0
Deduct 725 from 807 and we're left with 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 145

Going ahead to step 7:
If we divide 828 by 145, we get 5 and a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 40355.0
Subtracting 725 from 828 leaves us with 103.
Grab the next digit (7) from the dividend, add it to 103, then carry on: 1037 / 145

Step 8:
145 can be fit into 1037 7 times, resulting in a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 403557.0
Subtracting 1015 from 1037 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
145 goes into 220 1 times with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 403557.1
If we subtract 145 from 220, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
145 can be fit into 750 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 403557.15
The remainder is 25 after subtracting 725 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
145 goes into 250 1 times with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 403557.151
If we subtract 145 from 250, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 12:
If we divide 1050 by 145, we get 7 and a remainder of 35.
The next digit of our result is 7. 
Result so far: 403557.1517
If we take 1015 away from 1050, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
The number 145 fits into 350 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 403557.15172
If we subtract 290 from 350, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
145 can be fit into 600 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 403557.151724
If we take 580 away from 600, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
145 can be fit into 200 1 times, resulting in a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 403557.1517241
Subtract 145 from 200 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 16:
The number 145 fits into 550 3 times, leaving a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 403557.15172413
Subtracting 435 from 550 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The quotient of the division is 403557.15172413, and the remainder is 1.15e-07.
