Let's divide 51573381 by 971
We want to figure out the number of times 51573381 can be divided by 971.

Moving on to step 1:
When dividing 5 by 971, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 971

Moving on to step 2:
The number 971 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 971

Let's proceed to step 3:
971 goes into 515 0 times with a remainder of 515.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 515 to get 515.
Take the next digit (7) from the dividend and append it to 515, then repeat: 5157 / 971

Moving on to step 4:
If we divide 5157 by 971, we get 5 and a remainder of 302.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4855 from 5157 leaves us with 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 971

Step 5:
971 goes into 3023 3 times with a remainder of 110.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 2913 from 3023 to get 110.
Take the next digit (3) from the dividend and append it to 110, then repeat: 1103 / 971

Advancing to step 6:
If we divide 1103 by 971, we get 1 and a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
If we subtract 971 from 1103, we get 132.
Take the next digit (8) from the dividend and append it to 132, then repeat: 1328 / 971

Step 7:
When dividing 1328 by 971, we get 1 with a remainder of 357.
The number 1 becomes the next digit in our result. 
Result so far: 5311.0
Subtract 971 from 1328 to get 357.
Append the next digit (1) from the dividend to 357 and continue with: 3571 / 971

Advancing to step 8:
If we divide 3571 by 971, we get 3 and a remainder of 658.
The next digit of our result is 3. 
Result so far: 53113.0
If we take 2913 away from 3571, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 9:
6580 divided by 971 is 6 with a remainder of 754.
Use 6 as the next digit of our solution. 
Result so far: 53113.6
If we subtract 5826 from 6580, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Advancing to step 10:
7540 divided by 971 is 7 with a remainder of 743.
Use 7 as the next digit of our solution. 
Result so far: 53113.67
Subtract 6797 from 7540 to get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Going ahead to step 11:
971 can be fit into 7430 7 times, resulting in a remainder of 633.
The next digit of our result is 7. 
Result so far: 53113.677
Deduct 6797 from 7430 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

The final outcome is 53113.677, with a leftover of 0.0633.
