25402660 divided by 420 
Let's see how many times 420 fits into 25402660.

Let's proceed to step 1:
420 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 420

On to step 2:
The number 420 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 420

Going ahead to step 3:
The number 420 fits into 254 0 times, leaving a remainder of 254.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 254, we get 254.
Bring next digit (0) of the dividend behind the 254 and repeat the process: 2540 / 420

Advancing to step 4:
420 goes into 2540 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 2520 from 2540 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 420

Advancing to step 5:
The number 420 fits into 202 0 times, leaving a remainder of 202.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 202 after subtracting 0 from 202.
Grab the next digit (6) from the dividend, add it to 202, then carry on: 2026 / 420

Let's proceed to step 6:
420 goes into 2026 4 times with a remainder of 346.
Use 4 as the next digit of our solution. 
Result so far: 604.0
Subtracting 1680 from 2026 leaves us with 346.
Append the next digit (6) from the dividend to 346 and continue with: 3466 / 420

Advancing to step 7:
420 goes into 3466 8 times with a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 6048.0
Deduct 3360 from 3466 and we're left with 106.
Include the next digit (0) from the dividend after 106, then repeat: 1060 / 420

Going ahead to step 8:
420 goes into 1060 2 times with a remainder of 220.
Record the quotient 2 as the next digit in the result. 
Result so far: 60482.0
Deduct 840 from 1060 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 9:
When dividing 2200 by 420, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 60482.5
The remainder is 100 after subtracting 2100 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
If we divide 1000 by 420, we get 2 and a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 60482.52
If we take 840 away from 1000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
When dividing 1600 by 420, we get 3 with a remainder of 340.
Record the quotient 3 as the next digit in the result. 
Result so far: 60482.523
Subtract 1260 from 1600 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
420 goes into 3400 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 60482.5238
If we take 3360 away from 3400, we end up 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.

On to step 13:
The number 420 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 60482.5238
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 14:
4000 divided by 420 is 9 with a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 60482.523809
If we take 3780 away from 4000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
420 can be fit into 2200 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 60482.5238095
Subtracting 2100 from 2200 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 16:
The number 420 fits into 1000 2 times, leaving a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 60482.52380952
Subtract 840 from 1000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 60482.52380952 with a remainder of 1.6e-07.
