58855480 ÷ 640 
Let's see how many times 640 fits into 58855480.

Step 1:
If we divide 5 by 640, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 640

Let's proceed to step 2:
When dividing 58 by 640, we get 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Include the next digit (8) from the dividend after 58, then repeat: 588 / 640

Step 3:
640 can be fit into 588 0 times, resulting in a remainder of 588.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 588, we end up with 588.
Include the next digit (5) from the dividend after 588, then repeat: 5885 / 640

Going ahead to step 4:
640 can be fit into 5885 9 times, resulting in a remainder of 125.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 125 after subtracting 5760 from 5885.
Grab the next digit (5) from the dividend, add it to 125, then carry on: 1255 / 640

Going ahead to step 5:
The number 640 fits into 1255 1 times, leaving a remainder of 615.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 640 from 1255 leaves us with 615.
Include the next digit (4) from the dividend after 615, then repeat: 6154 / 640

Advancing to step 6:
640 can be fit into 6154 9 times, resulting in a remainder of 394.
The number 9 becomes the next digit in our result. 
Result so far: 919.0
Deduct 5760 from 6154 and we're left with 394.
Fetch the next digit (8) from the dividend, attach it to 394 and continue: 3948 / 640

Let's proceed to step 7:
The number 640 fits into 3948 6 times, leaving a remainder of 108.
The next digit of our result is 6. 
Result so far: 9196.0
Subtract 3840 from 3948 to get 108.
Grab the next digit (0) from the dividend, add it to 108, then carry on: 1080 / 640

Advancing to step 8:
When dividing 1080 by 640, we get 1 with a remainder of 440.
The number 1 becomes the next digit in our result. 
Result so far: 91961.0
If we take 640 away from 1080, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 9:
When dividing 4400 by 640, we get 6 with a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 91961.6
If we take 3840 away from 4400, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 10:
640 can be fit into 5600 8 times, resulting in a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 91961.68
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.

Moving on to step 11:
If we divide 4800 by 640, we get 7 and a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 91961.687
Subtract 4480 from 4800 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
3200 divided by 640 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 91961.6875
If we subtract 3200 from 3200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
640 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 91961.6875
If we take 0 away from 0, we end up 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.

On to step 14:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 91961.6875
Subtract 0 from 0 to get 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 91961.6875, with a leftover of 0.0.
