25137586 divided by 971 
We want to figure out the number of times 25137586 can be divided by 971.

On to step 1:
The number 971 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 971

Moving on to step 2:
The number 971 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 971

Advancing to step 3:
971 can be fit into 251 0 times, resulting in a remainder of 251.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 251 leaves us with 251.
Append the next digit (3) from the dividend to 251 and continue with: 2513 / 971

Let's proceed to step 4:
971 goes into 2513 2 times with a remainder of 571.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1942 from 2513 and we're left with 571.
Take the next digit (7) from the dividend and append it to 571, then repeat: 5717 / 971

Moving on to step 5:
971 goes into 5717 5 times with a remainder of 862.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 4855 from 5717, we get 862.
Include the next digit (5) from the dividend after 862, then repeat: 8625 / 971

Advancing to step 6:
When dividing 8625 by 971, we get 8 with a remainder of 857.
Put 8 as the next digit of the answer. 
Result so far: 258.0
Subtracting 7768 from 8625 leaves us with 857.
Include the next digit (8) from the dividend after 857, then repeat: 8578 / 971

Moving on to step 7:
When dividing 8578 by 971, we get 8 with a remainder of 810.
Write down 8 as next digit of the result. 
Result so far: 2588.0
If we take 7768 away from 8578, we end up with 810.
Bring next digit (6) of the dividend behind the 810 and repeat the process: 8106 / 971

Moving on to step 8:
If we divide 8106 by 971, we get 8 and a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 25888.0
If we subtract 7768 from 8106, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 9:
The number 971 fits into 3380 3 times, leaving a remainder of 467.
Write down 3 as next digit of the result. 
Result so far: 25888.3
The remainder is 467 after subtracting 2913 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 10:
4670 divided by 971 is 4 with a remainder of 786.
Write down 4 as next digit of the result. 
Result so far: 25888.34
If we take 3884 away from 4670, we end up with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Advancing to step 11:
7860 divided by 971 is 8 with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 25888.348
Subtracting 7768 from 7860 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
If we divide 920 by 971, we get 0 and a remainder of 920.
Put 0 as the next digit of the answer. 
Result so far: 25888.348
Deduct 0 from 920 and we're left with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Advancing to step 13:
When dividing 9200 by 971, we get 9 with a remainder of 461.
The number 9 becomes the next digit in our result. 
Result so far: 25888.34809
If we take 8739 away from 9200, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 14:
971 goes into 4610 4 times with a remainder of 726.
Put 4 as the next digit of the answer. 
Result so far: 25888.348094
If we take 3884 away from 4610, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Advancing to step 15:
971 goes into 7260 7 times with a remainder of 463.
Write down 7 as next digit of the result. 
Result so far: 25888.3480947
If we subtract 6797 from 7260, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 16:
971 goes into 4630 4 times with a remainder of 746.
The number 4 becomes the next digit in our result. 
Result so far: 25888.34809474
Subtracting 3884 from 4630 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

The final outcome is 25888.34809474, with a leftover of 7.46e-07.
