39245761 ÷ 158 
Let's see how many times 158 fits into 39245761.

On to step 1:
The number 158 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 158

Going ahead to step 2:
158 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 158

On to step 3:
If we divide 392 by 158, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 316 from 392 and we're left with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 158

Step 4:
If we divide 764 by 158, we get 4 and a remainder of 132.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 632 from 764, we get 132.
Take the next digit (5) from the dividend and append it to 132, then repeat: 1325 / 158

Moving on to step 5:
158 can be fit into 1325 8 times, resulting in a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
Subtract 1264 from 1325 to get 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 158

Going ahead to step 6:
158 goes into 617 3 times with a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 2483.0
The remainder is 143 after subtracting 474 from 617.
Take the next digit (6) from the dividend and append it to 143, then repeat: 1436 / 158

On to step 7:
If we divide 1436 by 158, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 24839.0
Deduct 1422 from 1436 and we're left with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 158

Let's proceed to step 8:
158 goes into 141 0 times with a remainder of 141.
Write down 0 as next digit of the result. 
Result so far: 248390.0
If we take 0 away from 141, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
If we divide 1410 by 158, we get 8 and a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 248390.8
If we take 1264 away from 1410, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 10:
158 can be fit into 1460 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 248390.89
Subtracting 1422 from 1460 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
158 goes into 380 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 248390.892
Subtract 316 from 380 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
158 goes into 640 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 248390.8924
Deduct 632 from 640 and we're left 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.

Step 13:
The number 158 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 248390.8924
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
158 can be fit into 800 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 248390.892405
The remainder is 10 after subtracting 790 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
158 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 248390.892405
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
158 can be fit into 1000 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 248390.89240506
The remainder is 52 after subtracting 948 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 248390.89240506 and a remainder of 5.2e-08.
