71581518 ÷ 351 
We want to figure out the number of times 71581518 can be divided by 351.

Moving on to step 1:
351 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 351

Going ahead to step 2:
If we divide 71 by 351, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 351

Going ahead to step 3:
When dividing 715 by 351, we get 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 702 from 715 leaves us with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 351

Going ahead to step 4:
138 divided by 351 is 0 with a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 138 leaves us with 138.
Bring next digit (1) of the dividend behind the 138 and repeat the process: 1381 / 351

Moving on to step 5:
1381 divided by 351 is 3 with a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we take 1053 away from 1381, we end up with 328.
Include the next digit (5) from the dividend after 328, then repeat: 3285 / 351

Going ahead to step 6:
351 can be fit into 3285 9 times, resulting in a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 2039.0
Subtract 3159 from 3285 to get 126.
Take the next digit (1) from the dividend and append it to 126, then repeat: 1261 / 351

Moving on to step 7:
351 can be fit into 1261 3 times, resulting in a remainder of 208.
Record the quotient 3 as the next digit in the result. 
Result so far: 20393.0
Deduct 1053 from 1261 and we're left with 208.
Take the next digit (8) from the dividend and append it to 208, then repeat: 2088 / 351

Advancing to step 8:
351 goes into 2088 5 times with a remainder of 333.
Record the quotient 5 as the next digit in the result. 
Result so far: 203935.0
If we subtract 1755 from 2088, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Step 9:
The number 351 fits into 3330 9 times, leaving a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 203935.9
Subtracting 3159 from 3330 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 10:
351 can be fit into 1710 4 times, resulting in a remainder of 306.
The next digit of our result is 4. 
Result so far: 203935.94
Subtracting 1404 from 1710 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 11:
If we divide 3060 by 351, we get 8 and a remainder of 252.
Record the quotient 8 as the next digit in the result. 
Result so far: 203935.948
If we take 2808 away from 3060, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
2520 divided by 351 is 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 203935.9487
If we take 2457 away from 2520, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 13:
351 goes into 630 1 times with a remainder of 279.
The next digit of our result is 1. 
Result so far: 203935.94871
Subtract 351 from 630 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 14:
351 goes into 2790 7 times with a remainder of 333.
The number 7 becomes the next digit in our result. 
Result so far: 203935.948717
If we subtract 2457 from 2790, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 15:
351 goes into 3330 9 times with a remainder of 171.
The next digit of our result is 9. 
Result so far: 203935.9487179
Subtracting 3159 from 3330 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 16:
When dividing 1710 by 351, we get 4 with a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 203935.94871794
Deduct 1404 from 1710 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

In conclusion, the division gives 203935.94871794 with a balance of 3.06e-07.
