58378911 ÷ 221 
We want to divide 58378911 by 221.

Advancing to step 1:
If we divide 5 by 221, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 221

Going ahead to step 2:
When dividing 58 by 221, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 221

On to step 3:
221 goes into 583 2 times with a remainder of 141.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 442 from 583, we get 141.
Take the next digit (7) from the dividend and append it to 141, then repeat: 1417 / 221

Going ahead to step 4:
221 can be fit into 1417 6 times, resulting in a remainder of 91.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 1326 from 1417 leaves us with 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 221

On to step 5:
When dividing 918 by 221, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 264.0
Deduct 884 from 918 and we're left with 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 221

On to step 6:
221 can be fit into 349 1 times, resulting in a remainder of 128.
The next digit of our result is 1. 
Result so far: 2641.0
Subtract 221 from 349 to get 128.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 221

Going ahead to step 7:
1281 divided by 221 is 5 with a remainder of 176.
Put 5 as the next digit of the answer. 
Result so far: 26415.0
Deduct 1105 from 1281 and we're left with 176.
Append the next digit (1) from the dividend to 176 and continue with: 1761 / 221

Going ahead to step 8:
When dividing 1761 by 221, we get 7 with a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 264157.0
The remainder is 214 after subtracting 1547 from 1761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 9:
If we divide 2140 by 221, we get 9 and a remainder of 151.
The next digit of our result is 9. 
Result so far: 264157.9
If we subtract 1989 from 2140, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 10:
When dividing 1510 by 221, we get 6 with a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 264157.96
The remainder is 184 after subtracting 1326 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 11:
The number 221 fits into 1840 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 264157.968
Deduct 1768 from 1840 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
If we divide 720 by 221, we get 3 and a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 264157.9683
Subtract 663 from 720 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 13:
221 can be fit into 570 2 times, resulting in a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 264157.96832
Deduct 442 from 570 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
If we divide 1280 by 221, we get 5 and a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 264157.968325
Subtracting 1105 from 1280 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 15:
When dividing 1750 by 221, we get 7 with a remainder of 203.
The next digit of our result is 7. 
Result so far: 264157.9683257
The remainder is 203 after subtracting 1547 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 16:
221 can be fit into 2030 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 264157.96832579
Deduct 1989 from 2030 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 264157.96832579, with a leftover of 4.1e-08.
