43780201 ÷ 221 
We're looking to find how many times 221 goes into 43780201.

Let's proceed to step 1:
If we divide 4 by 221, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 221

Advancing to step 2:
43 divided by 221 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 221

On to step 3:
If we divide 437 by 221, we get 1 and a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 216 after subtracting 221 from 437.
Include the next digit (8) from the dividend after 216, then repeat: 2168 / 221

Moving on to step 4:
When dividing 2168 by 221, we get 9 with a remainder of 179.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 1989 from 2168 and we're left with 179.
Grab the next digit (0) from the dividend, add it to 179, then carry on: 1790 / 221

Advancing to step 5:
When dividing 1790 by 221, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
Subtracting 1768 from 1790 leaves us with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 221

Going ahead to step 6:
If we divide 222 by 221, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1981.0
If we take 221 away from 222, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 221

Going ahead to step 7:
10 divided by 221 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 19810.0
If we take 0 away from 10, we end up with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 221

Advancing to step 8:
When dividing 101 by 221, we get 0 with a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 198100.0
If we subtract 0 from 101, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 9:
1010 divided by 221 is 4 with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 198100.4
Subtracting 884 from 1010 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
When dividing 1260 by 221, we get 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 198100.45
The remainder is 155 after subtracting 1105 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 11:
If we divide 1550 by 221, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 198100.457
If we take 1547 away from 1550, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
221 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 198100.457
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
221 goes into 300 1 times with a remainder of 79.
The next digit of our result is 1. 
Result so far: 198100.45701
The remainder is 79 after subtracting 221 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 14:
790 divided by 221 is 3 with a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 198100.457013
If we take 663 away from 790, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 15:
If we divide 1270 by 221, we get 5 and a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 198100.4570135
The remainder is 165 after subtracting 1105 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 16:
221 goes into 1650 7 times with a remainder of 103.
The next digit of our result is 7. 
Result so far: 198100.45701357
Subtract 1547 from 1650 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final outcome is 198100.45701357, with a leftover of 1.03e-07.
