We look at the division of 58387903 by 660 
Our goal is to divide 58387903 by 660.

On to step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 660

Step 2:
The number 660 fits into 58 0 times, leaving a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 660

On to step 3:
The number 660 fits into 583 0 times, leaving a remainder of 583.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 583 leaves us with 583.
Append the next digit (8) from the dividend to 583 and continue with: 5838 / 660

Advancing to step 4:
When dividing 5838 by 660, we get 8 with a remainder of 558.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 558 after subtracting 5280 from 5838.
Append the next digit (7) from the dividend to 558 and continue with: 5587 / 660

Going ahead to step 5:
5587 divided by 660 is 8 with a remainder of 307.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 5280 from 5587 leaves us with 307.
Append the next digit (9) from the dividend to 307 and continue with: 3079 / 660

Moving on to step 6:
When dividing 3079 by 660, we get 4 with a remainder of 439.
The next digit of our result is 4. 
Result so far: 884.0
If we take 2640 away from 3079, we end up with 439.
Grab the next digit (0) from the dividend, add it to 439, then carry on: 4390 / 660

Advancing to step 7:
If we divide 4390 by 660, we get 6 and a remainder of 430.
The next digit of our result is 6. 
Result so far: 8846.0
The remainder is 430 after subtracting 3960 from 4390.
Take the next digit (3) from the dividend and append it to 430, then repeat: 4303 / 660

Moving on to step 8:
660 goes into 4303 6 times with a remainder of 343.
Put 6 as the next digit of the answer. 
Result so far: 88466.0
Subtracting 3960 from 4303 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 9:
660 can be fit into 3430 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 88466.5
The remainder is 130 after subtracting 3300 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
When dividing 1300 by 660, we get 1 with a remainder of 640.
The next digit of our result is 1. 
Result so far: 88466.51
Subtracting 660 from 1300 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 11:
660 goes into 6400 9 times with a remainder of 460.
The number 9 becomes the next digit in our result. 
Result so far: 88466.519
Deduct 5940 from 6400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
If we divide 4600 by 660, we get 6 and a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 88466.5196
Subtracting 3960 from 4600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
The number 660 fits into 6400 9 times, leaving a remainder of 460.
Use 9 as the next digit of our solution. 
Result so far: 88466.51969
Deduct 5940 from 6400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 14:
If we divide 4600 by 660, we get 6 and a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 88466.519696
Subtracting 3960 from 4600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
The number 660 fits into 6400 9 times, leaving a remainder of 460.
Put 9 as the next digit of the answer. 
Result so far: 88466.5196969
Subtract 5940 from 6400 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
If we divide 4600 by 660, we get 6 and a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 88466.51969696
The remainder is 640 after subtracting 3960 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 88466.51969696, with a leftover of 6.4e-07.
