51978232 ÷ 448 
We're looking to find how many times 448 goes into 51978232.

Step 1:
If we divide 5 by 448, 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 448

Step 2:
51 divided by 448 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 448

Moving on to step 3:
448 can be fit into 519 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 448 from 519 and we're left with 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 448

Advancing to step 4:
If we divide 717 by 448, we get 1 and a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 448 away from 717, we end up with 269.
Take the next digit (8) from the dividend and append it to 269, then repeat: 2698 / 448

Advancing to step 5:
When dividing 2698 by 448, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 2688 from 2698 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 448

Moving on to step 6:
102 divided by 448 is 0 with a remainder of 102.
Put 0 as the next digit of the answer. 
Result so far: 1160.0
Subtracting 0 from 102 leaves us with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 448

On to step 7:
The number 448 fits into 1023 2 times, leaving a remainder of 127.
Use 2 as the next digit of our solution. 
Result so far: 11602.0
Subtract 896 from 1023 to get 127.
Append the next digit (2) from the dividend to 127 and continue with: 1272 / 448

On to step 8:
448 goes into 1272 2 times with a remainder of 376.
The next digit of our result is 2. 
Result so far: 116022.0
The remainder is 376 after subtracting 896 from 1272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 9:
448 goes into 3760 8 times with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 116022.8
Subtracting 3584 from 3760 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
When dividing 1760 by 448, we get 3 with a remainder of 416.
Write down 3 as next digit of the result. 
Result so far: 116022.83
If we subtract 1344 from 1760, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 11:
448 goes into 4160 9 times with a remainder of 128.
The next digit of our result is 9. 
Result so far: 116022.839
Subtracting 4032 from 4160 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
448 can be fit into 1280 2 times, resulting in a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 116022.8392
If we subtract 896 from 1280, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 13:
3840 divided by 448 is 8 with a remainder of 256.
The next digit of our result is 8. 
Result so far: 116022.83928
Subtracting 3584 from 3840 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 14:
When dividing 2560 by 448, we get 5 with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 116022.839285
Subtracting 2240 from 2560 leaves us with 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 448, we get 7 with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 116022.8392857
Subtracting 3136 from 3200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
If we divide 640 by 448, we get 1 and a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 116022.83928571
Subtract 448 from 640 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

In conclusion, the division gives 116022.83928571 with a balance of 1.92e-07.
