2153849 ÷ 158 
Let's see how many times 158 fits into 2153849.

On to step 1:
2 divided by 158 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 158

Step 2:
If we divide 21 by 158, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 158

Advancing to step 3:
215 divided by 158 is 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 158 from 215 leaves us with 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 158

Advancing to step 4:
If we divide 573 by 158, we get 3 and a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 99 after subtracting 474 from 573.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 158

Advancing to step 5:
If we divide 998 by 158, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 136.0
The remainder is 50 after subtracting 948 from 998.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 158

On to step 6:
If we divide 504 by 158, we get 3 and a remainder of 30.
The next digit of our result is 3. 
Result so far: 1363.0
Subtracting 474 from 504 leaves us with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 158

Let's proceed to step 7:
309 divided by 158 is 1 with a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 13631.0
Subtract 158 from 309 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 8:
The number 158 fits into 1510 9 times, leaving a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 13631.9
If we subtract 1422 from 1510, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
If we divide 880 by 158, we get 5 and a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 13631.95
Deduct 790 from 880 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
158 goes into 900 5 times with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 13631.955
If we subtract 790 from 900, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 13631.955, and the remainder is 0.011.
