56105315 ÷ 448 
We want to figure out the number of times 56105315 can be divided by 448.

On to step 1:
When dividing 5 by 448, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 448

On to step 2:
448 goes into 56 0 times with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 448

Advancing to step 3:
448 goes into 561 1 times with a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 448 from 561, we get 113.
Take the next digit (0) from the dividend and append it to 113, then repeat: 1130 / 448

Step 4:
The number 448 fits into 1130 2 times, leaving a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 234 after subtracting 896 from 1130.
Take the next digit (5) from the dividend and append it to 234, then repeat: 2345 / 448

Advancing to step 5:
2345 divided by 448 is 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 2240 from 2345, we get 105.
Take the next digit (3) from the dividend and append it to 105, then repeat: 1053 / 448

On to step 6:
The number 448 fits into 1053 2 times, leaving a remainder of 157.
The next digit of our result is 2. 
Result so far: 1252.0
Subtracting 896 from 1053 leaves us with 157.
Append the next digit (1) from the dividend to 157 and continue with: 1571 / 448

Step 7:
448 can be fit into 1571 3 times, resulting in a remainder of 227.
Write down 3 as next digit of the result. 
Result so far: 12523.0
The remainder is 227 after subtracting 1344 from 1571.
Include the next digit (5) from the dividend after 227, then repeat: 2275 / 448

Step 8:
When dividing 2275 by 448, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 125235.0
The remainder is 35 after subtracting 2240 from 2275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
The number 448 fits into 350 0 times, leaving a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 125235.0
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
448 goes into 3500 7 times with a remainder of 364.
Record the quotient 7 as the next digit in the result. 
Result so far: 125235.07
If we take 3136 away from 3500, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
448 goes into 3640 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 125235.078
Subtract 3584 from 3640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
560 divided by 448 is 1 with a remainder of 112.
Put 1 as the next digit of the answer. 
Result so far: 125235.0781
Subtracting 448 from 560 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
If we divide 1120 by 448, we get 2 and a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 125235.07812
Subtracting 896 from 1120 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
448 goes into 2240 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 125235.078125
Subtracting 2240 from 2240 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.

Going ahead to step 15:
448 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 125235.078125
If we subtract 0 from 0, 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.

Let's proceed to step 16:
448 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 125235.078125
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.

The final outcome is 125235.078125, with a leftover of 0.0.
