87971548 ÷ 830 
We want to figure out the number of times 87971548 can be divided by 830.

Let's proceed to step 1:
830 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 830

Step 2:
The number 830 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 830

On to step 3:
If we divide 879 by 830, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 49 after subtracting 830 from 879.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 830

Going ahead to step 4:
497 divided by 830 is 0 with a remainder of 497.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 497 leaves us with 497.
Include the next digit (1) from the dividend after 497, then repeat: 4971 / 830

Let's proceed to step 5:
4971 divided by 830 is 5 with a remainder of 821.
Write down 5 as next digit of the result. 
Result so far: 105.0
The remainder is 821 after subtracting 4150 from 4971.
Fetch the next digit (5) from the dividend, attach it to 821 and continue: 8215 / 830

Step 6:
The number 830 fits into 8215 9 times, leaving a remainder of 745.
The number 9 becomes the next digit in our result. 
Result so far: 1059.0
Subtract 7470 from 8215 to get 745.
Grab the next digit (4) from the dividend, add it to 745, then carry on: 7454 / 830

Moving on to step 7:
830 goes into 7454 8 times with a remainder of 814.
The next digit of our result is 8. 
Result so far: 10598.0
Subtract 6640 from 7454 to get 814.
Take the next digit (8) from the dividend and append it to 814, then repeat: 8148 / 830

Going ahead to step 8:
8148 divided by 830 is 9 with a remainder of 678.
Record the quotient 9 as the next digit in the result. 
Result so far: 105989.0
Subtracting 7470 from 8148 leaves us with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Advancing to step 9:
When dividing 6780 by 830, we get 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 105989.8
The remainder is 140 after subtracting 6640 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
When dividing 1400 by 830, we get 1 with a remainder of 570.
Write down 1 as next digit of the result. 
Result so far: 105989.81
Subtracting 830 from 1400 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 11:
The number 830 fits into 5700 6 times, leaving a remainder of 720.
Use 6 as the next digit of our solution. 
Result so far: 105989.816
Subtracting 4980 from 5700 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 12:
830 goes into 7200 8 times with a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 105989.8168
Subtracting 6640 from 7200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
830 goes into 5600 6 times with a remainder of 620.
Put 6 as the next digit of the answer. 
Result so far: 105989.81686
Subtracting 4980 from 5600 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
6200 divided by 830 is 7 with a remainder of 390.
The next digit of our result is 7. 
Result so far: 105989.816867
Subtracting 5810 from 6200 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 15:
The number 830 fits into 3900 4 times, leaving a remainder of 580.
Use 4 as the next digit of our solution. 
Result so far: 105989.8168674
If we subtract 3320 from 3900, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 16:
830 can be fit into 5800 6 times, resulting in a remainder of 820.
Use 6 as the next digit of our solution. 
Result so far: 105989.81686746
If we subtract 4980 from 5800, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

The final result is 105989.81686746 with a remainder of 8.2e-07.
