We look at the division of 25152506 by 39 
We want to figure out the number of times 25152506 can be divided by 39.

On to step 1:
39 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 39

Moving on to step 2:
39 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 39

Advancing to step 3:
251 divided by 39 is 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 234 from 251, we get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 39

On to step 4:
39 goes into 175 4 times with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 156 away from 175, we end up with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 39

Advancing to step 5:
192 divided by 39 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 644.0
If we subtract 156 from 192, we get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 39

Let's proceed to step 6:
39 can be fit into 365 9 times, resulting in a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 6449.0
Subtracting 351 from 365 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 39

Advancing to step 7:
140 divided by 39 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 64493.0
If we subtract 117 from 140, we get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 39

Advancing to step 8:
The number 39 fits into 236 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 644936.0
Subtracting 234 from 236 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 39, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 644936.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 39 fits into 200 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 644936.05
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
50 divided by 39 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 644936.051
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
If we divide 110 by 39, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 644936.0512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
The number 39 fits into 320 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 644936.05128
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 39, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 644936.051282
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
When dividing 20 by 39, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 644936.051282
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
When dividing 200 by 39, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 644936.05128205
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 644936.05128205 with a balance of 5e-09.
