21177719 ÷ 355 
We're looking to find how many times 355 goes into 21177719.

Going ahead to step 1:
355 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 355

On to step 2:
21 divided by 355 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 355

Advancing to step 3:
355 can be fit into 211 0 times, resulting in a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Append the next digit (7) from the dividend to 211 and continue with: 2117 / 355

Let's proceed to step 4:
The number 355 fits into 2117 5 times, leaving a remainder of 342.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 1775 from 2117 to get 342.
Append the next digit (7) from the dividend to 342 and continue with: 3427 / 355

On to step 5:
3427 divided by 355 is 9 with a remainder of 232.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 3195 from 3427 to get 232.
Fetch the next digit (7) from the dividend, attach it to 232 and continue: 2327 / 355

Advancing to step 6:
355 can be fit into 2327 6 times, resulting in a remainder of 197.
Use 6 as the next digit of our solution. 
Result so far: 596.0
If we take 2130 away from 2327, we end up with 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 355

Advancing to step 7:
If we divide 1971 by 355, we get 5 and a remainder of 196.
The number 5 becomes the next digit in our result. 
Result so far: 5965.0
The remainder is 196 after subtracting 1775 from 1971.
Fetch the next digit (9) from the dividend, attach it to 196 and continue: 1969 / 355

On to step 8:
The number 355 fits into 1969 5 times, leaving a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 59655.0
Subtracting 1775 from 1969 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 9:
1940 divided by 355 is 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 59655.5
If we subtract 1775 from 1940, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
If we divide 1650 by 355, we get 4 and a remainder of 230.
The next digit of our result is 4. 
Result so far: 59655.54
If we subtract 1420 from 1650, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
If we divide 2300 by 355, we get 6 and a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 59655.546
Deduct 2130 from 2300 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 12:
355 goes into 1700 4 times with a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 59655.5464
If we take 1420 away from 1700, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
When dividing 2800 by 355, we get 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 59655.54647
Subtracting 2485 from 2800 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 14:
The number 355 fits into 3150 8 times, leaving a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 59655.546478
Deduct 2840 from 3150 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
355 goes into 3100 8 times with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 59655.5464788
Subtracting 2840 from 3100 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 59655.5464788 with a balance of 2.6e-06.
