64143177 ÷ 353 
Our goal is to divide 64143177 by 353.

On to step 1:
If we divide 6 by 353, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 353

Moving on to step 2:
If we divide 64 by 353, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 353

Let's proceed to step 3:
641 divided by 353 is 1 with a remainder of 288.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 353 from 641 leaves us with 288.
Grab the next digit (4) from the dividend, add it to 288, then carry on: 2884 / 353

Step 4:
353 goes into 2884 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 2824 from 2884, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 353

Moving on to step 5:
603 divided by 353 is 1 with a remainder of 250.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Subtract 353 from 603 to get 250.
Fetch the next digit (1) from the dividend, attach it to 250 and continue: 2501 / 353

Going ahead to step 6:
353 goes into 2501 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 1817.0
Subtracting 2471 from 2501 leaves us with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 353

Advancing to step 7:
When dividing 307 by 353, we get 0 with a remainder of 307.
The next digit of our result is 0. 
Result so far: 18170.0
Subtract 0 from 307 to get 307.
Include the next digit (7) from the dividend after 307, then repeat: 3077 / 353

Step 8:
The number 353 fits into 3077 8 times, leaving a remainder of 253.
Put 8 as the next digit of the answer. 
Result so far: 181708.0
If we take 2824 away from 3077, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
2530 divided by 353 is 7 with a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 181708.7
Deduct 2471 from 2530 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
When dividing 590 by 353, we get 1 with a remainder of 237.
Put 1 as the next digit of the answer. 
Result so far: 181708.71
Subtracting 353 from 590 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 11:
353 can be fit into 2370 6 times, resulting in a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 181708.716
The remainder is 252 after subtracting 2118 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 12:
353 goes into 2520 7 times with a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 181708.7167
If we subtract 2471 from 2520, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
When dividing 490 by 353, we get 1 with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 181708.71671
Subtracting 353 from 490 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 14:
If we divide 1370 by 353, we get 3 and a remainder of 311.
The next digit of our result is 3. 
Result so far: 181708.716713
Subtract 1059 from 1370 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 15:
353 goes into 3110 8 times with a remainder of 286.
The number 8 becomes the next digit in our result. 
Result so far: 181708.7167138
If we take 2824 away from 3110, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 16:
353 can be fit into 2860 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 181708.71671388
Deduct 2824 from 2860 and we're left 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.

The final result is 181708.71671388 with a remainder of 3.6e-08.
