We're dividing 42102092 by 153 
We want to divide 42102092 by 153.

Advancing to step 1:
153 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 153

Advancing to step 2:
If we divide 42 by 153, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 153

On to step 3:
421 divided by 153 is 2 with a remainder of 115.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 306 from 421, we get 115.
Append the next digit (0) from the dividend to 115 and continue with: 1150 / 153

On to step 4:
153 goes into 1150 7 times with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 1071 from 1150 to get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 153

Let's proceed to step 5:
When dividing 792 by 153, we get 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 275.0
Subtract 765 from 792 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 153

Going ahead to step 6:
The number 153 fits into 270 1 times, leaving a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 2751.0
Subtracting 153 from 270 leaves us with 117.
Append the next digit (9) from the dividend to 117 and continue with: 1179 / 153

Going ahead to step 7:
1179 divided by 153 is 7 with a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 27517.0
If we subtract 1071 from 1179, we get 108.
Fetch the next digit (2) from the dividend, attach it to 108 and continue: 1082 / 153

Moving on to step 8:
153 goes into 1082 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 275177.0
Deduct 1071 from 1082 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 153, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 275177.0
Subtract 0 from 110 to 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.

Going ahead to step 10:
1100 divided by 153 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 275177.07
If we subtract 1071 from 1100, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
When dividing 290 by 153, we get 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 275177.071
Subtracting 153 from 290 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
153 can be fit into 1370 8 times, resulting in a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 275177.0718
If we subtract 1224 from 1370, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 13:
The number 153 fits into 1460 9 times, leaving a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 275177.07189
Subtracting 1377 from 1460 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 14:
830 divided by 153 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 275177.071895
Subtract 765 from 830 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 15:
650 divided by 153 is 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 275177.0718954
If we subtract 612 from 650, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 16:
The number 153 fits into 380 2 times, leaving a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 275177.07189542
Subtracting 306 from 380 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 275177.07189542 with a remaining 7.4e-08.
