Let's divide 75566904 by 221
Our goal is to divide 75566904 by 221.

Going ahead to step 1:
When dividing 7 by 221, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 221

Moving on to step 2:
221 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 221

Step 3:
The number 221 fits into 755 3 times, leaving a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 663 away from 755, we end up with 92.
Include the next digit (6) from the dividend after 92, then repeat: 926 / 221

On to step 4:
The number 221 fits into 926 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 884 from 926 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 221

Let's proceed to step 5:
426 divided by 221 is 1 with a remainder of 205.
The next digit of our result is 1. 
Result so far: 341.0
Deduct 221 from 426 and we're left with 205.
Append the next digit (9) from the dividend to 205 and continue with: 2059 / 221

Going ahead to step 6:
221 can be fit into 2059 9 times, resulting in a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 3419.0
Deduct 1989 from 2059 and we're left with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 221

Advancing to step 7:
221 goes into 700 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 34193.0
Subtracting 663 from 700 leaves us with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 221

Going ahead to step 8:
The number 221 fits into 374 1 times, leaving a remainder of 153.
The next digit of our result is 1. 
Result so far: 341931.0
Subtracting 221 from 374 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
The number 221 fits into 1530 6 times, leaving a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 341931.6
If we take 1326 away from 1530, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
2040 divided by 221 is 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 341931.69
Subtracting 1989 from 2040 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 11:
When dividing 510 by 221, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 341931.692
Deduct 442 from 510 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
If we divide 680 by 221, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 341931.6923
If we take 663 away from 680, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
221 can be fit into 170 0 times, resulting in a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 341931.6923
If we take 0 away from 170, 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.

Let's proceed to step 14:
221 can be fit into 1700 7 times, resulting in a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 341931.692307
Deduct 1547 from 1700 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 15:
1530 divided by 221 is 6 with a remainder of 204.
Use 6 as the next digit of our solution. 
Result so far: 341931.6923076
Deduct 1326 from 1530 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 16:
The number 221 fits into 2040 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 341931.69230769
The remainder is 51 after subtracting 1989 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 341931.69230769 with a remainder of 5.1e-08.
