We look at the division of 25374493 by 602 
We want to divide 25374493 by 602.

Moving on to step 1:
If we divide 2 by 602, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 602

Moving on to step 2:
When dividing 25 by 602, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 602

Going ahead to step 3:
If we divide 253 by 602, we get 0 and a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 253 leaves us with 253.
Grab the next digit (7) from the dividend, add it to 253, then carry on: 2537 / 602

Let's proceed to step 4:
If we divide 2537 by 602, we get 4 and a remainder of 129.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2408 from 2537 and we're left with 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 602

On to step 5:
If we divide 1294 by 602, we get 2 and a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 1204 from 1294 to get 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 602

Moving on to step 6:
602 can be fit into 904 1 times, resulting in a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 421.0
Subtracting 602 from 904 leaves us with 302.
Include the next digit (9) from the dividend after 302, then repeat: 3029 / 602

On to step 7:
If we divide 3029 by 602, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 4215.0
The remainder is 19 after subtracting 3010 from 3029.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 602

Step 8:
602 goes into 193 0 times with a remainder of 193.
The next digit of our result is 0. 
Result so far: 42150.0
Subtract 0 from 193 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 9:
The number 602 fits into 1930 3 times, leaving a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 42150.3
Subtract 1806 from 1930 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 10:
1240 divided by 602 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 42150.32
If we take 1204 away from 1240, we end up 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.

Going ahead to step 11:
When dividing 360 by 602, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 42150.32
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
3600 divided by 602 is 5 with a remainder of 590.
The next digit of our result is 5. 
Result so far: 42150.3205
Subtracting 3010 from 3600 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 13:
5900 divided by 602 is 9 with a remainder of 482.
Write down 9 as next digit of the result. 
Result so far: 42150.32059
Deduct 5418 from 5900 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 14:
602 goes into 4820 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 42150.320598
Deduct 4816 from 4820 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 15:
602 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 42150.320598
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
602 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 42150.320598
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 42150.320598 with a remaining 4e-07.
