We're dividing 58160190 by 640 
Our goal is to divide 58160190 by 640.

Moving on to step 1:
The number 640 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
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 / 640

Let's proceed to step 2:
If we divide 58 by 640, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 640

Going ahead to step 3:
581 divided by 640 is 0 with a remainder of 581.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 581 after subtracting 0 from 581.
Fetch the next digit (6) from the dividend, attach it to 581 and continue: 5816 / 640

Let's proceed to step 4:
5816 divided by 640 is 9 with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 5760 from 5816 and we're left with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 640

On to step 5:
When dividing 560 by 640, we get 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 560 to get 560.
Fetch the next digit (1) from the dividend, attach it to 560 and continue: 5601 / 640

Going ahead to step 6:
640 can be fit into 5601 8 times, resulting in a remainder of 481.
The number 8 becomes the next digit in our result. 
Result so far: 908.0
If we take 5120 away from 5601, we end up with 481.
Grab the next digit (9) from the dividend, add it to 481, then carry on: 4819 / 640

Going ahead to step 7:
640 goes into 4819 7 times with a remainder of 339.
The next digit of our result is 7. 
Result so far: 9087.0
The remainder is 339 after subtracting 4480 from 4819.
Bring next digit (0) of the dividend behind the 339 and repeat the process: 3390 / 640

Let's proceed to step 8:
The number 640 fits into 3390 5 times, leaving a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 90875.0
If we subtract 3200 from 3390, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
If we divide 1900 by 640, we get 2 and a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 90875.2
Subtract 1280 from 1900 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 10:
6200 divided by 640 is 9 with a remainder of 440.
The next digit of our result is 9. 
Result so far: 90875.29
Subtract 5760 from 6200 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
If we divide 4400 by 640, we get 6 and a remainder of 560.
Use 6 as the next digit of our solution. 
Result so far: 90875.296
If we subtract 3840 from 4400, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 12:
5600 divided by 640 is 8 with a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 90875.2968
If we take 5120 away from 5600, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
4800 divided by 640 is 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 90875.29687
The remainder is 320 after subtracting 4480 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
When dividing 3200 by 640, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 90875.296875
Subtracting 3200 from 3200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90875.296875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
0 divided by 640 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90875.296875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 90875.296875, with a leftover of 0.0.
