77794546 ÷ 221 
Let's see how many times 221 fits into 77794546.

Moving on to step 1:
7 divided by 221 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 221

Advancing to step 2:
221 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 221

Going ahead to step 3:
777 divided by 221 is 3 with a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 663 from 777 leaves us with 114.
Take the next digit (9) from the dividend and append it to 114, then repeat: 1149 / 221

Step 4:
The number 221 fits into 1149 5 times, leaving a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 1105 from 1149 leaves us with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 221

Going ahead to step 5:
If we divide 444 by 221, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 352.0
Subtract 442 from 444 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 221

Moving on to step 6:
221 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 3520.0
If we subtract 0 from 25, we get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 221

Let's proceed to step 7:
221 goes into 254 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 35201.0
Deduct 221 from 254 and we're left with 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 221

Moving on to step 8:
The number 221 fits into 336 1 times, leaving a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 352011.0
The remainder is 115 after subtracting 221 from 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
If we divide 1150 by 221, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 352011.5
Subtract 1105 from 1150 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 221, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 352011.52
If we subtract 442 from 450, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 221 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 352011.52
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
800 divided by 221 is 3 with a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 352011.5203
If we subtract 663 from 800, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 13:
The number 221 fits into 1370 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 352011.52036
Subtract 1326 from 1370 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
221 goes into 440 1 times with a remainder of 219.
The next digit of our result is 1. 
Result so far: 352011.520361
If we subtract 221 from 440, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 15:
When dividing 2190 by 221, we get 9 with a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 352011.5203619
If we take 1989 away from 2190, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 16:
When dividing 2010 by 221, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 352011.52036199
Subtracting 1989 from 2010 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 352011.52036199, with a leftover of 2.1e-08.
