48121265 ÷ 640 
We're looking to find how many times 640 goes into 48121265.

Let's proceed to step 1:
640 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 640

Moving on to step 2:
640 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 640

On to step 3:
The number 640 fits into 481 0 times, leaving a remainder of 481.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 481 to get 481.
Include the next digit (2) from the dividend after 481, then repeat: 4812 / 640

On to step 4:
When dividing 4812 by 640, we get 7 with a remainder of 332.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 4480 from 4812 to get 332.
Grab the next digit (1) from the dividend, add it to 332, then carry on: 3321 / 640

Moving on to step 5:
640 can be fit into 3321 5 times, resulting in a remainder of 121.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 121 after subtracting 3200 from 3321.
Take the next digit (2) from the dividend and append it to 121, then repeat: 1212 / 640

Going ahead to step 6:
The number 640 fits into 1212 1 times, leaving a remainder of 572.
Use 1 as the next digit of our solution. 
Result so far: 751.0
If we subtract 640 from 1212, we get 572.
Append the next digit (6) from the dividend to 572 and continue with: 5726 / 640

Step 7:
The number 640 fits into 5726 8 times, leaving a remainder of 606.
Write down 8 as next digit of the result. 
Result so far: 7518.0
If we subtract 5120 from 5726, we get 606.
Append the next digit (5) from the dividend to 606 and continue with: 6065 / 640

Step 8:
640 goes into 6065 9 times with a remainder of 305.
Put 9 as the next digit of the answer. 
Result so far: 75189.0
If we take 5760 away from 6065, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 9:
640 goes into 3050 4 times with a remainder of 490.
Use 4 as the next digit of our solution. 
Result so far: 75189.4
Deduct 2560 from 3050 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 10:
When dividing 4900 by 640, we get 7 with a remainder of 420.
Put 7 as the next digit of the answer. 
Result so far: 75189.47
If we take 4480 away from 4900, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
The number 640 fits into 4200 6 times, leaving a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 75189.476
The remainder is 360 after subtracting 3840 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
When dividing 3600 by 640, we get 5 with a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 75189.4765
Deduct 3200 from 3600 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
4000 divided by 640 is 6 with a remainder of 160.
The next digit of our result is 6. 
Result so far: 75189.47656
Subtracting 3840 from 4000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
If we divide 1600 by 640, we get 2 and a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 75189.476562
If we subtract 1280 from 1600, we 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.

Moving on to step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 75189.4765625
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.

On to step 16:
0 divided by 640 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 75189.4765625
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 quotient of the division is 75189.4765625, and the remainder is 0.0.
