53455757 ÷ 200 
Let's see how many times 200 fits into 53455757.

Step 1:
200 goes into 5 0 times 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.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 200

Moving on to step 2:
The number 200 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 200

On to step 3:
200 goes into 534 2 times with a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 400 from 534 to get 134.
Bring next digit (5) of the dividend behind the 134 and repeat the process: 1345 / 200

Moving on to step 4:
The number 200 fits into 1345 6 times, leaving a remainder of 145.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 1200 away from 1345, we end up with 145.
Include the next digit (5) from the dividend after 145, then repeat: 1455 / 200

Step 5:
200 can be fit into 1455 7 times, resulting in a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 267.0
Subtracting 1400 from 1455 leaves us with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 200

Advancing to step 6:
The number 200 fits into 557 2 times, leaving a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 2672.0
If we take 400 away from 557, we end up with 157.
Append the next digit (5) from the dividend to 157 and continue with: 1575 / 200

Advancing to step 7:
200 goes into 1575 7 times with a remainder of 175.
Write down 7 as next digit of the result. 
Result so far: 26727.0
If we take 1400 away from 1575, we end up with 175.
Bring next digit (7) of the dividend behind the 175 and repeat the process: 1757 / 200

Going ahead to step 8:
If we divide 1757 by 200, we get 8 and a remainder of 157.
Use 8 as the next digit of our solution. 
Result so far: 267278.0
If we take 1600 away from 1757, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
The number 200 fits into 1570 7 times, leaving a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 267278.7
If we take 1400 away from 1570, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
If we divide 1700 by 200, we get 8 and a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 267278.78
Subtracting 1600 from 1700 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
If we divide 1000 by 200, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 267278.785
Subtract 1000 from 1000 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 12:
When dividing 0 by 200, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 267278.785
Subtracting 0 from 0 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.

Step 13:
200 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 267278.785
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 267278.785, with a leftover of 0.0.
