50261515 ÷ 400 
Let's see how many times 400 fits into 50261515.

Step 1:
When dividing 5 by 400, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 400

Step 2:
50 divided by 400 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 400

Step 3:
400 can be fit into 502 1 times, resulting in a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 400 from 502 leaves us with 102.
Fetch the next digit (6) from the dividend, attach it to 102 and continue: 1026 / 400

Step 4:
400 goes into 1026 2 times with a remainder of 226.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 226 after subtracting 800 from 1026.
Grab the next digit (1) from the dividend, add it to 226, then carry on: 2261 / 400

Advancing to step 5:
When dividing 2261 by 400, we get 5 with a remainder of 261.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 2000 from 2261 and we're left with 261.
Bring next digit (5) of the dividend behind the 261 and repeat the process: 2615 / 400

Moving on to step 6:
2615 divided by 400 is 6 with a remainder of 215.
Record the quotient 6 as the next digit in the result. 
Result so far: 1256.0
The remainder is 215 after subtracting 2400 from 2615.
Grab the next digit (1) from the dividend, add it to 215, then carry on: 2151 / 400

Moving on to step 7:
2151 divided by 400 is 5 with a remainder of 151.
Put 5 as the next digit of the answer. 
Result so far: 12565.0
If we subtract 2000 from 2151, we get 151.
Fetch the next digit (5) from the dividend, attach it to 151 and continue: 1515 / 400

On to step 8:
1515 divided by 400 is 3 with a remainder of 315.
The next digit of our result is 3. 
Result so far: 125653.0
If we take 1200 away from 1515, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 9:
The number 400 fits into 3150 7 times, leaving a remainder of 350.
The next digit of our result is 7. 
Result so far: 125653.7
Deduct 2800 from 3150 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
The number 400 fits into 3500 8 times, leaving a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 125653.78
The remainder is 300 after subtracting 3200 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
When dividing 3000 by 400, we get 7 with a remainder of 200.
Write down 7 as next digit of the result. 
Result so far: 125653.787
Subtracting 2800 from 3000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 125653.7875
Subtract 2000 from 2000 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.

Going ahead to step 13:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 125653.7875
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.

Moving on to step 14:
When dividing 0 by 400, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 125653.7875
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.

In conclusion, the division gives 125653.7875 with a balance of 0.0.
