16665821 ÷ 353 
We want to divide 16665821 by 353.

Going ahead to step 1:
The number 353 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 353

Advancing to step 2:
353 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 353

Moving on to step 3:
166 divided by 353 is 0 with a remainder of 166.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 166 leaves us with 166.
Bring next digit (6) of the dividend behind the 166 and repeat the process: 1666 / 353

Advancing to step 4:
353 can be fit into 1666 4 times, resulting in a remainder of 254.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1412 from 1666 to get 254.
Include the next digit (5) from the dividend after 254, then repeat: 2545 / 353

Going ahead to step 5:
If we divide 2545 by 353, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 74 after subtracting 2471 from 2545.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 353

Let's proceed to step 6:
748 divided by 353 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 472.0
Subtract 706 from 748 to get 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 353

Step 7:
The number 353 fits into 422 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 4721.0
If we take 353 away from 422, we end up with 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 353

On to step 8:
691 divided by 353 is 1 with a remainder of 338.
The next digit of our result is 1. 
Result so far: 47211.0
Deduct 353 from 691 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 9:
353 goes into 3380 9 times with a remainder of 203.
Record the quotient 9 as the next digit in the result. 
Result so far: 47211.9
If we take 3177 away from 3380, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 10:
If we divide 2030 by 353, we get 5 and a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 47211.95
The remainder is 265 after subtracting 1765 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 11:
When dividing 2650 by 353, we get 7 with a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 47211.957
Subtract 2471 from 2650 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 12:
When dividing 1790 by 353, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 47211.9575
If we subtract 1765 from 1790, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
250 divided by 353 is 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 47211.9575
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
353 goes into 2500 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 47211.957507
Deduct 2471 from 2500 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 15:
290 divided by 353 is 0 with a remainder of 290.
The next digit of our result is 0. 
Result so far: 47211.957507
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 16:
The number 353 fits into 2900 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 47211.95750708
The remainder is 76 after subtracting 2824 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 47211.95750708, and the remainder is 7.6e-08.
