81945575 divided by 971 
We're looking to find how many times 971 goes into 81945575.

Going ahead to step 1:
8 divided by 971 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 971

Step 2:
971 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 971

Going ahead to step 3:
971 can be fit into 819 0 times, resulting in a remainder of 819.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 819 after subtracting 0 from 819.
Include the next digit (4) from the dividend after 819, then repeat: 8194 / 971

Step 4:
When dividing 8194 by 971, we get 8 with a remainder of 426.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7768 from 8194 and we're left with 426.
Fetch the next digit (5) from the dividend, attach it to 426 and continue: 4265 / 971

Going ahead to step 5:
971 goes into 4265 4 times with a remainder of 381.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 3884 from 4265 leaves us with 381.
Include the next digit (5) from the dividend after 381, then repeat: 3815 / 971

Going ahead to step 6:
3815 divided by 971 is 3 with a remainder of 902.
The number 3 becomes the next digit in our result. 
Result so far: 843.0
The remainder is 902 after subtracting 2913 from 3815.
Bring next digit (7) of the dividend behind the 902 and repeat the process: 9027 / 971

Moving on to step 7:
When dividing 9027 by 971, we get 9 with a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 8439.0
If we subtract 8739 from 9027, we get 288.
Append the next digit (5) from the dividend to 288 and continue with: 2885 / 971

Let's proceed to step 8:
If we divide 2885 by 971, we get 2 and a remainder of 943.
Put 2 as the next digit of the answer. 
Result so far: 84392.0
If we take 1942 away from 2885, we end up with 943.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

Going ahead to step 9:
971 can be fit into 9430 9 times, resulting in a remainder of 691.
Write down 9 as next digit of the result. 
Result so far: 84392.9
Subtract 8739 from 9430 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 10:
If we divide 6910 by 971, we get 7 and a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 84392.97
If we take 6797 away from 6910, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 11:
1130 divided by 971 is 1 with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 84392.971
Deduct 971 from 1130 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 12:
1590 divided by 971 is 1 with a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 84392.9711
Subtract 971 from 1590 to get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

After the division, we end up with 84392.9711 and a remainder of 0.00619.
