43354148 divided by 221 
We want to figure out the number of times 43354148 can be divided by 221.

On to step 1:
4 divided by 221 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 221

Moving on to step 2:
When dividing 43 by 221, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 221

Advancing to step 3:
221 goes into 433 1 times with a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 221 from 433, we get 212.
Append the next digit (5) from the dividend to 212 and continue with: 2125 / 221

Going ahead to step 4:
If we divide 2125 by 221, we get 9 and a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 1989 from 2125, we get 136.
Fetch the next digit (4) from the dividend, attach it to 136 and continue: 1364 / 221

Advancing to step 5:
1364 divided by 221 is 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 196.0
If we take 1326 away from 1364, we end up with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 221

Going ahead to step 6:
221 goes into 381 1 times with a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 1961.0
The remainder is 160 after subtracting 221 from 381.
Bring next digit (4) of the dividend behind the 160 and repeat the process: 1604 / 221

On to step 7:
When dividing 1604 by 221, we get 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 19617.0
The remainder is 57 after subtracting 1547 from 1604.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 221

Step 8:
If we divide 578 by 221, we get 2 and a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 196172.0
If we subtract 442 from 578, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 9:
221 goes into 1360 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 196172.6
The remainder is 34 after subtracting 1326 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 221, we get 1 and a remainder of 119.
The next digit of our result is 1. 
Result so far: 196172.61
Subtracting 221 from 340 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 11:
If we divide 1190 by 221, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 196172.615
Subtracting 1105 from 1190 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
221 goes into 850 3 times with a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 196172.6153
Subtract 663 from 850 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 13:
The number 221 fits into 1870 8 times, leaving a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 196172.61538
If we take 1768 away from 1870, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 14:
When dividing 1020 by 221, we get 4 with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 196172.615384
Deduct 884 from 1020 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 15:
If we divide 1360 by 221, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 196172.6153846
Subtracting 1326 from 1360 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 16:
340 divided by 221 is 1 with a remainder of 119.
The next digit of our result is 1. 
Result so far: 196172.61538461
Deduct 221 from 340 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The final result is 196172.61538461 with a remainder of 1.19e-07.
