We divide 25039407 by 420
We want to figure out the number of times 25039407 can be divided by 420.

Moving on to step 1:
When dividing 2 by 420, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 420

Let's proceed to step 2:
When dividing 25 by 420, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 420

Going ahead to step 3:
420 goes into 250 0 times with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 250 and we're left with 250.
Fetch the next digit (3) from the dividend, attach it to 250 and continue: 2503 / 420

Step 4:
The number 420 fits into 2503 5 times, leaving a remainder of 403.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 403 after subtracting 2100 from 2503.
Include the next digit (9) from the dividend after 403, then repeat: 4039 / 420

Step 5:
The number 420 fits into 4039 9 times, leaving a remainder of 259.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 3780 from 4039 and we're left with 259.
Append the next digit (4) from the dividend to 259 and continue with: 2594 / 420

Step 6:
When dividing 2594 by 420, we get 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 596.0
If we take 2520 away from 2594, we end up with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 420

Step 7:
740 divided by 420 is 1 with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 5961.0
Subtracting 420 from 740 leaves us with 320.
Take the next digit (7) from the dividend and append it to 320, then repeat: 3207 / 420

On to step 8:
The number 420 fits into 3207 7 times, leaving a remainder of 267.
The number 7 becomes the next digit in our result. 
Result so far: 59617.0
If we take 2940 away from 3207, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 9:
If we divide 2670 by 420, we get 6 and a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 59617.6
If we take 2520 away from 2670, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 420 fits into 1500 3 times, leaving a remainder of 240.
Record the quotient 3 as the next digit in the result. 
Result so far: 59617.63
Subtract 1260 from 1500 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
When dividing 2400 by 420, we get 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 59617.635
Subtracting 2100 from 2400 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 12:
When dividing 3000 by 420, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 59617.6357
The remainder is 60 after subtracting 2940 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
600 divided by 420 is 1 with a remainder of 180.
The next digit of our result is 1. 
Result so far: 59617.63571
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
The number 420 fits into 1800 4 times, leaving a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 59617.635714
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
420 can be fit into 1200 2 times, resulting in a remainder of 360.
The next digit of our result is 2. 
Result so far: 59617.6357142
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 16:
If we divide 3600 by 420, we get 8 and a remainder of 240.
The next digit of our result is 8. 
Result so far: 59617.63571428
If we subtract 3360 from 3600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 59617.63571428 with a remaining 2.4e-07.
