We look at the division of 53757617 by 221 
We want to figure out the number of times 53757617 can be divided by 221.

On to step 1:
If we divide 5 by 221, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 221

Going ahead to step 2:
When dividing 53 by 221, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 221

Going ahead to step 3:
221 can be fit into 537 2 times, resulting in a remainder of 95.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 95 after subtracting 442 from 537.
Append the next digit (5) from the dividend to 95 and continue with: 955 / 221

Advancing to step 4:
955 divided by 221 is 4 with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 884 from 955, we get 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 221

Moving on to step 5:
221 can be fit into 717 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 243.0
Subtract 663 from 717 to get 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 221

On to step 6:
546 divided by 221 is 2 with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 2432.0
Subtract 442 from 546 to get 104.
Append the next digit (1) from the dividend to 104 and continue with: 1041 / 221

Moving on to step 7:
The number 221 fits into 1041 4 times, leaving a remainder of 157.
The number 4 becomes the next digit in our result. 
Result so far: 24324.0
If we take 884 away from 1041, we end up with 157.
Append the next digit (7) from the dividend to 157 and continue with: 1577 / 221

Let's proceed to step 8:
When dividing 1577 by 221, we get 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 243247.0
The remainder is 30 after subtracting 1547 from 1577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
221 goes into 300 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 243247.1
If we subtract 221 from 300, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 10:
790 divided by 221 is 3 with a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 243247.13
Subtract 663 from 790 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 11:
The number 221 fits into 1270 5 times, leaving a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 243247.135
If we take 1105 away from 1270, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 12:
If we divide 1650 by 221, we get 7 and a remainder of 103.
Record the quotient 7 as the next digit in the result. 
Result so far: 243247.1357
Subtracting 1547 from 1650 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 13:
1030 divided by 221 is 4 with a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 243247.13574
The remainder is 146 after subtracting 884 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 14:
The number 221 fits into 1460 6 times, leaving a remainder of 134.
The next digit of our result is 6. 
Result so far: 243247.135746
Subtract 1326 from 1460 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 15:
1340 divided by 221 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 243247.1357466
Subtract 1326 from 1340 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 243247.1357466 with a remaining 1.4e-07.
