39791415 ÷ 259 
We want to divide 39791415 by 259.

Let's proceed to step 1:
3 divided by 259 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 259

On to step 2:
When dividing 39 by 259, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 259

Step 3:
259 can be fit into 397 1 times, resulting in a remainder of 138.
The next digit of our result is 1. 
Result so far: 1.0
If we take 259 away from 397, we end up with 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 259

Let's proceed to step 4:
When dividing 1389 by 259, we get 5 with a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 1295 from 1389 leaves us with 94.
Bring next digit (1) of the dividend behind the 94 and repeat the process: 941 / 259

Advancing to step 5:
259 can be fit into 941 3 times, resulting in a remainder of 164.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we take 777 away from 941, we end up with 164.
Fetch the next digit (4) from the dividend, attach it to 164 and continue: 1644 / 259

Step 6:
259 can be fit into 1644 6 times, resulting in a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 1536.0
Subtract 1554 from 1644 to get 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 259

Advancing to step 7:
When dividing 901 by 259, we get 3 with a remainder of 124.
Put 3 as the next digit of the answer. 
Result so far: 15363.0
Deduct 777 from 901 and we're left with 124.
Fetch the next digit (5) from the dividend, attach it to 124 and continue: 1245 / 259

Let's proceed to step 8:
259 can be fit into 1245 4 times, resulting in a remainder of 209.
Record the quotient 4 as the next digit in the result. 
Result so far: 153634.0
If we take 1036 away from 1245, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
The number 259 fits into 2090 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 153634.8
Deduct 2072 from 2090 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
The number 259 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 153634.8
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
If we divide 1800 by 259, we get 6 and a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 153634.806
The remainder is 246 after subtracting 1554 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 12:
259 can be fit into 2460 9 times, resulting in a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 153634.8069
Subtract 2331 from 2460 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 13:
1290 divided by 259 is 4 with a remainder of 254.
The next digit of our result is 4. 
Result so far: 153634.80694
Deduct 1036 from 1290 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 14:
The number 259 fits into 2540 9 times, leaving a remainder of 209.
The next digit of our result is 9. 
Result so far: 153634.806949
Deduct 2331 from 2540 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 15:
When dividing 2090 by 259, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 153634.8069498
The remainder is 18 after subtracting 2072 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 16:
When dividing 180 by 259, we get 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 153634.8069498
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 153634.8069498, with a leftover of 1.8e-07.
