71542989 ÷ 819 
Our goal is to divide 71542989 by 819.

Advancing to step 1:
When dividing 7 by 819, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 819

Going ahead to step 2:
When dividing 71 by 819, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 819

Moving on to step 3:
If we divide 715 by 819, we get 0 and a remainder of 715.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 715 after subtracting 0 from 715.
Bring next digit (4) of the dividend behind the 715 and repeat the process: 7154 / 819

On to step 4:
819 can be fit into 7154 8 times, resulting in a remainder of 602.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6552 away from 7154, we end up with 602.
Append the next digit (2) from the dividend to 602 and continue with: 6022 / 819

On to step 5:
If we divide 6022 by 819, we get 7 and a remainder of 289.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 5733 from 6022 and we're left with 289.
Fetch the next digit (9) from the dividend, attach it to 289 and continue: 2899 / 819

Let's proceed to step 6:
819 can be fit into 2899 3 times, resulting in a remainder of 442.
Put 3 as the next digit of the answer. 
Result so far: 873.0
The remainder is 442 after subtracting 2457 from 2899.
Grab the next digit (8) from the dividend, add it to 442, then carry on: 4428 / 819

Moving on to step 7:
When dividing 4428 by 819, we get 5 with a remainder of 333.
The number 5 becomes the next digit in our result. 
Result so far: 8735.0
If we take 4095 away from 4428, we end up with 333.
Include the next digit (9) from the dividend after 333, then repeat: 3339 / 819

Going ahead to step 8:
819 goes into 3339 4 times with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 87354.0
Subtract 3276 from 3339 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
819 can be fit into 630 0 times, resulting in a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 87354.0
The remainder is 630 after subtracting 0 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 10:
6300 divided by 819 is 7 with a remainder of 567.
The number 7 becomes the next digit in our result. 
Result so far: 87354.07
Subtracting 5733 from 6300 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 11:
5670 divided by 819 is 6 with a remainder of 756.
Record the quotient 6 as the next digit in the result. 
Result so far: 87354.076
The remainder is 756 after subtracting 4914 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 12:
7560 divided by 819 is 9 with a remainder of 189.
Put 9 as the next digit of the answer. 
Result so far: 87354.0769
If we take 7371 away from 7560, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 13:
819 goes into 1890 2 times with a remainder of 252.
Record the quotient 2 as the next digit in the result. 
Result so far: 87354.07692
If we subtract 1638 from 1890, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 14:
The number 819 fits into 2520 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 87354.076923
Subtracting 2457 from 2520 leaves us 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 15:
819 can be fit into 630 0 times, resulting in a remainder of 630.
The next digit of our result is 0. 
Result so far: 87354.076923
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 16:
If we divide 6300 by 819, we get 7 and a remainder of 567.
Record the quotient 7 as the next digit in the result. 
Result so far: 87354.07692307
Subtracting 5733 from 6300 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

The final outcome is 87354.07692307, with a leftover of 5.67e-07.
