66310779 ÷ 214 
Our goal is to divide 66310779 by 214.

On to step 1:
214 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 214

On to step 2:
214 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 214

On to step 3:
214 can be fit into 663 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 642 away from 663, we end up with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 214

On to step 4:
214 can be fit into 211 0 times, resulting in a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 211 to get 211.
Include the next digit (0) from the dividend after 211, then repeat: 2110 / 214

Moving on to step 5:
214 can be fit into 2110 9 times, resulting in a remainder of 184.
The next digit of our result is 9. 
Result so far: 309.0
Subtract 1926 from 2110 to get 184.
Append the next digit (7) from the dividend to 184 and continue with: 1847 / 214

Moving on to step 6:
If we divide 1847 by 214, we get 8 and a remainder of 135.
The number 8 becomes the next digit in our result. 
Result so far: 3098.0
Subtract 1712 from 1847 to get 135.
Include the next digit (7) from the dividend after 135, then repeat: 1357 / 214

On to step 7:
214 goes into 1357 6 times with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 30986.0
If we subtract 1284 from 1357, we get 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 214

Step 8:
739 divided by 214 is 3 with a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 309863.0
The remainder is 97 after subtracting 642 from 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
When dividing 970 by 214, we get 4 with a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 309863.4
Subtract 856 from 970 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 10:
When dividing 1140 by 214, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 309863.45
Subtracting 1070 from 1140 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
If we divide 700 by 214, we get 3 and a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 309863.453
Deduct 642 from 700 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
If we divide 580 by 214, we get 2 and a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 309863.4532
Subtracting 428 from 580 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 13:
If we divide 1520 by 214, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 309863.45327
If we subtract 1498 from 1520, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
220 divided by 214 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 309863.453271
The remainder is 6 after subtracting 214 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 15:
60 divided by 214 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 309863.453271
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
214 can be fit into 600 2 times, resulting in a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 309863.45327102
Deduct 428 from 600 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 309863.45327102, with a leftover of 1.72e-07.
