58154719 ÷ 387 
The aim is to understand the frequency of 387 in 58154719.

Moving on to step 1:
387 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 387

Let's proceed to step 2:
387 can be fit into 58 0 times, resulting in a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 387

Going ahead to step 3:
If we divide 581 by 387, we get 1 and a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 387 from 581 leaves us with 194.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 387

Moving on to step 4:
387 goes into 1945 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 1935 from 1945 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 387

Going ahead to step 5:
104 divided by 387 is 0 with a remainder of 104.
The next digit of our result is 0. 
Result so far: 150.0
If we subtract 0 from 104, we get 104.
Append the next digit (7) from the dividend to 104 and continue with: 1047 / 387

Moving on to step 6:
387 goes into 1047 2 times with a remainder of 273.
Put 2 as the next digit of the answer. 
Result so far: 1502.0
Deduct 774 from 1047 and we're left with 273.
Fetch the next digit (1) from the dividend, attach it to 273 and continue: 2731 / 387

Let's proceed to step 7:
387 goes into 2731 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 15027.0
If we subtract 2709 from 2731, we get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 387

Let's proceed to step 8:
387 can be fit into 229 0 times, resulting in a remainder of 229.
The number 0 becomes the next digit in our result. 
Result so far: 150270.0
If we subtract 0 from 229, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 9:
387 goes into 2290 5 times with a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 150270.5
Subtract 1935 from 2290 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 10:
If we divide 3550 by 387, we get 9 and a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 150270.59
If we take 3483 away from 3550, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
When dividing 670 by 387, we get 1 with a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 150270.591
Deduct 387 from 670 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 12:
2830 divided by 387 is 7 with a remainder of 121.
Put 7 as the next digit of the answer. 
Result so far: 150270.5917
Subtracting 2709 from 2830 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 13:
When dividing 1210 by 387, we get 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 150270.59173
If we take 1161 away from 1210, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
If we divide 490 by 387, we get 1 and a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 150270.591731
The remainder is 103 after subtracting 387 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 15:
387 goes into 1030 2 times with a remainder of 256.
The next digit of our result is 2. 
Result so far: 150270.5917312
Subtract 774 from 1030 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 16:
387 goes into 2560 6 times with a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 150270.59173126
If we take 2322 away from 2560, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 150270.59173126, with a leftover of 2.38e-07.
