81516463 ÷ 671 
We want to figure out the number of times 81516463 can be divided by 671.

Moving on to step 1:
8 divided by 671 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 671

On to step 2:
If we divide 81 by 671, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 671

On to step 3:
When dividing 815 by 671, we get 1 with a remainder of 144.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 671 from 815 and we're left with 144.
Take the next digit (1) from the dividend and append it to 144, then repeat: 1441 / 671

Moving on to step 4:
If we divide 1441 by 671, we get 2 and a remainder of 99.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1342 from 1441 leaves us with 99.
Grab the next digit (6) from the dividend, add it to 99, then carry on: 996 / 671

Step 5:
671 goes into 996 1 times with a remainder of 325.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtracting 671 from 996 leaves us with 325.
Append the next digit (4) from the dividend to 325 and continue with: 3254 / 671

Let's proceed to step 6:
671 goes into 3254 4 times with a remainder of 570.
Write down 4 as next digit of the result. 
Result so far: 1214.0
Deduct 2684 from 3254 and we're left with 570.
Grab the next digit (6) from the dividend, add it to 570, then carry on: 5706 / 671

On to step 7:
When dividing 5706 by 671, we get 8 with a remainder of 338.
The number 8 becomes the next digit in our result. 
Result so far: 12148.0
Subtract 5368 from 5706 to get 338.
Include the next digit (3) from the dividend after 338, then repeat: 3383 / 671

On to step 8:
3383 divided by 671 is 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 121485.0
The remainder is 28 after subtracting 3355 from 3383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
280 divided by 671 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 121485.0
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
When dividing 2800 by 671, we get 4 with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 121485.04
Subtract 2684 from 2800 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
1160 divided by 671 is 1 with a remainder of 489.
Write down 1 as next digit of the result. 
Result so far: 121485.041
The remainder is 489 after subtracting 671 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 12:
4890 divided by 671 is 7 with a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 121485.0417
If we subtract 4697 from 4890, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 13:
671 goes into 1930 2 times with a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 121485.04172
Subtracting 1342 from 1930 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 14:
When dividing 5880 by 671, we get 8 with a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 121485.041728
If we take 5368 away from 5880, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 15:
The number 671 fits into 5120 7 times, leaving a remainder of 423.
The next digit of our result is 7. 
Result so far: 121485.0417287
If we subtract 4697 from 5120, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 16:
When dividing 4230 by 671, we get 6 with a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 121485.04172876
Deduct 4026 from 4230 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

After the division, we end up with 121485.04172876 and a remainder of 2.04e-07.
