53872499 ÷ 266 
We want to figure out the number of times 53872499 can be divided by 266.

Step 1:
When dividing 5 by 266, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 266

Moving on to step 2:
When dividing 53 by 266, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 266

On to step 3:
538 divided by 266 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 532 from 538 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 266

Step 4:
67 divided by 266 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 266

Advancing to step 5:
When dividing 672 by 266, we get 2 with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtract 532 from 672 to get 140.
Append the next digit (4) from the dividend to 140 and continue with: 1404 / 266

Moving on to step 6:
When dividing 1404 by 266, we get 5 with a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 2025.0
Subtracting 1330 from 1404 leaves us with 74.
Grab the next digit (9) from the dividend, add it to 74, then carry on: 749 / 266

Moving on to step 7:
If we divide 749 by 266, we get 2 and a remainder of 217.
Record the quotient 2 as the next digit in the result. 
Result so far: 20252.0
If we take 532 away from 749, we end up with 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 266

Advancing to step 8:
2179 divided by 266 is 8 with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 202528.0
If we subtract 2128 from 2179, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
266 can be fit into 510 1 times, resulting in a remainder of 244.
The number 1 becomes the next digit in our result. 
Result so far: 202528.1
If we subtract 266 from 510, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 10:
2440 divided by 266 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 202528.19
Deduct 2394 from 2440 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
266 can be fit into 460 1 times, resulting in a remainder of 194.
The next digit of our result is 1. 
Result so far: 202528.191
Deduct 266 from 460 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 12:
1940 divided by 266 is 7 with a remainder of 78.
The next digit of our result is 7. 
Result so far: 202528.1917
Deduct 1862 from 1940 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
266 can be fit into 780 2 times, resulting in a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 202528.19172
If we take 532 away from 780, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
2480 divided by 266 is 9 with a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 202528.191729
Subtracting 2394 from 2480 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 15:
266 goes into 860 3 times with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 202528.1917293
Deduct 798 from 860 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 16:
266 can be fit into 620 2 times, resulting in a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 202528.19172932
Subtract 532 from 620 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 202528.19172932, and the remainder is 8.8e-08.
