We're dividing 34201035 by 123 
We want to divide 34201035 by 123.

Going ahead to step 1:
The number 123 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 123

Moving on to step 2:
The number 123 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 123

Moving on to step 3:
If we divide 342 by 123, we get 2 and a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 246 away from 342, we end up with 96.
Bring next digit (0) of the dividend behind the 96 and repeat the process: 960 / 123

Let's proceed to step 4:
The number 123 fits into 960 7 times, leaving a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 861 from 960 leaves us with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 123

Advancing to step 5:
123 goes into 991 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
If we take 984 away from 991, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 123

Let's proceed to step 6:
123 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 2780.0
If we take 0 away from 70, we end up with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 123

On to step 7:
123 goes into 703 5 times with a remainder of 88.
Put 5 as the next digit of the answer. 
Result so far: 27805.0
If we take 615 away from 703, we end up with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 123

Going ahead to step 8:
885 divided by 123 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 278057.0
Subtracting 861 from 885 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
When dividing 240 by 123, we get 1 with a remainder of 117.
The next digit of our result is 1. 
Result so far: 278057.1
The remainder is 117 after subtracting 123 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 10:
123 can be fit into 1170 9 times, resulting in a remainder of 63.
The next digit of our result is 9. 
Result so far: 278057.19
Deduct 1107 from 1170 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 11:
123 goes into 630 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 278057.195
If we subtract 615 from 630, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
If we divide 150 by 123, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 278057.1951
Subtracting 123 from 150 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
When dividing 270 by 123, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 278057.19512
Subtract 246 from 270 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 123 is 1 with a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 278057.195121
Subtracting 123 from 240 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 15:
123 goes into 1170 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 278057.1951219
Subtract 1107 from 1170 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 16:
123 goes into 630 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 278057.19512195
Deduct 615 from 630 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 278057.19512195, and the remainder is 1.5e-08.
