48975718 ÷ 81 
Let's see how many times 81 fits into 48975718.

Step 1:
81 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 81

Moving on to step 2:
81 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 81

On to step 3:
If we divide 489 by 81, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 486 from 489 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 81

Moving on to step 4:
When dividing 37 by 81, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 81

Advancing to step 5:
375 divided by 81 is 4 with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 604.0
Subtract 324 from 375 to get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 81

On to step 6:
The number 81 fits into 517 6 times, leaving a remainder of 31.
The next digit of our result is 6. 
Result so far: 6046.0
The remainder is 31 after subtracting 486 from 517.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 81

Advancing to step 7:
311 divided by 81 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 60463.0
Subtracting 243 from 311 leaves us with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 81

Advancing to step 8:
If we divide 688 by 81, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 604638.0
If we take 648 away from 688, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 81, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 604638.4
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
When dividing 760 by 81, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 604638.49
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
81 goes into 310 3 times with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 604638.493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
81 goes into 670 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 604638.4938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 81 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 604638.49382
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 604638.493827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 15:
If we divide 130 by 81, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 604638.4938271
If we subtract 81 from 130, 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.

Moving on to step 16:
If we divide 490 by 81, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 604638.49382716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 604638.49382716, and the remainder is 4e-09.
