93667406 ÷ 221 
We want to figure out the number of times 93667406 can be divided by 221.

Advancing to step 1:
221 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 221

On to step 2:
The number 221 fits into 93 0 times, leaving a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Fetch the next digit (6) from the dividend, attach it to 93 and continue: 936 / 221

Let's proceed to step 3:
936 divided by 221 is 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 884 from 936, we get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 221

Advancing to step 4:
526 divided by 221 is 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 442 from 526 to get 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 221

On to step 5:
221 can be fit into 847 3 times, resulting in a remainder of 184.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Subtract 663 from 847 to get 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 221

Going ahead to step 6:
221 goes into 1844 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 4238.0
Deduct 1768 from 1844 and we're left with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 221

Advancing to step 7:
If we divide 760 by 221, we get 3 and a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 42383.0
If we subtract 663 from 760, we get 97.
Append the next digit (6) from the dividend to 97 and continue with: 976 / 221

Advancing to step 8:
The number 221 fits into 976 4 times, leaving a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 423834.0
If we take 884 away from 976, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 9:
221 goes into 920 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 423834.4
Subtracting 884 from 920 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
360 divided by 221 is 1 with a remainder of 139.
Put 1 as the next digit of the answer. 
Result so far: 423834.41
Subtract 221 from 360 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 11:
If we divide 1390 by 221, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 423834.416
The remainder is 64 after subtracting 1326 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
If we divide 640 by 221, we get 2 and a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 423834.4162
If we subtract 442 from 640, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 13:
1980 divided by 221 is 8 with a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 423834.41628
Deduct 1768 from 1980 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 14:
If we divide 2120 by 221, we get 9 and a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 423834.416289
Subtracting 1989 from 2120 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 15:
The number 221 fits into 1310 5 times, leaving a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 423834.4162895
If we subtract 1105 from 1310, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 16:
221 goes into 2050 9 times with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 423834.41628959
If we take 1989 away from 2050, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 423834.41628959 with a remainder of 6.1e-08.
