150858 ÷ 49 
We're looking to find how many times 49 goes into 150858.

Let's proceed to step 1:
If we divide 1 by 49, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 49

Advancing to step 2:
The number 49 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 49

Moving on to step 3:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 147 from 150 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 49

Going ahead to step 4:
When dividing 38 by 49, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 38, we get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 49

On to step 5:
The number 49 fits into 385 7 times, leaving a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 307.0
If we take 343 away from 385, we end up with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 49

On to step 6:
49 goes into 428 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 3078.0
Deduct 392 from 428 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 3078.7
Subtract 343 from 360 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
49 can be fit into 170 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 3078.73
Subtracting 147 from 170 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
The number 49 fits into 230 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 3078.734
Deduct 196 from 230 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
The number 49 fits into 340 6 times, leaving a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 3078.7346
Subtract 294 from 340 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
The number 49 fits into 460 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 3078.73469
Deduct 441 from 460 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
49 can be fit into 190 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 3078.734693
Deduct 147 from 190 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
49 can be fit into 430 8 times, resulting in a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 3078.7346938
Subtracting 392 from 430 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.

Going ahead to step 14:
49 goes into 380 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 3078.73469387
Subtract 343 from 380 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 3078.73469387 with a remainder of 3.7e-08.
