43061543 ÷ 353 
Let's see how many times 353 fits into 43061543.

Going ahead to step 1:
When dividing 4 by 353, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 353

Moving on to step 2:
When dividing 43 by 353, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 353

Step 3:
When dividing 430 by 353, we get 1 with a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 353 from 430 leaves us with 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 353

Moving on to step 4:
353 goes into 776 2 times with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 706 from 776, we get 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 353

Moving on to step 5:
When dividing 701 by 353, we get 1 with a remainder of 348.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Deduct 353 from 701 and we're left with 348.
Fetch the next digit (5) from the dividend, attach it to 348 and continue: 3485 / 353

Advancing to step 6:
3485 divided by 353 is 9 with a remainder of 308.
Use 9 as the next digit of our solution. 
Result so far: 1219.0
Subtract 3177 from 3485 to get 308.
Bring next digit (4) of the dividend behind the 308 and repeat the process: 3084 / 353

Advancing to step 7:
When dividing 3084 by 353, we get 8 with a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 12198.0
Subtract 2824 from 3084 to get 260.
Grab the next digit (3) from the dividend, add it to 260, then carry on: 2603 / 353

Moving on to step 8:
353 goes into 2603 7 times with a remainder of 132.
The next digit of our result is 7. 
Result so far: 121987.0
Deduct 2471 from 2603 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 9:
1320 divided by 353 is 3 with a remainder of 261.
The number 3 becomes the next digit in our result. 
Result so far: 121987.3
Subtract 1059 from 1320 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 10:
353 goes into 2610 7 times with a remainder of 139.
The next digit of our result is 7. 
Result so far: 121987.37
If we take 2471 away from 2610, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 11:
If we divide 1390 by 353, we get 3 and a remainder of 331.
Record the quotient 3 as the next digit in the result. 
Result so far: 121987.373
The remainder is 331 after subtracting 1059 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 12:
3310 divided by 353 is 9 with a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 121987.3739
Deduct 3177 from 3310 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 13:
353 goes into 1330 3 times with a remainder of 271.
The next digit of our result is 3. 
Result so far: 121987.37393
Subtract 1059 from 1330 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 14:
353 can be fit into 2710 7 times, resulting in a remainder of 239.
The next digit of our result is 7. 
Result so far: 121987.373937
Deduct 2471 from 2710 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 15:
If we divide 2390 by 353, we get 6 and a remainder of 272.
Use 6 as the next digit of our solution. 
Result so far: 121987.3739376
If we take 2118 away from 2390, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 16:
2720 divided by 353 is 7 with a remainder of 249.
The next digit of our result is 7. 
Result so far: 121987.37393767
If we take 2471 away from 2720, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

After the division, we end up with 121987.37393767 and a remainder of 2.49e-07.
