26886514 ÷ 420 
Our goal is to divide 26886514 by 420.

Step 1:
When dividing 2 by 420, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 420

Step 2:
When dividing 26 by 420, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 420

Let's proceed to step 3:
When dividing 268 by 420, we get 0 with a remainder of 268.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 268 and we're left with 268.
Append the next digit (8) from the dividend to 268 and continue with: 2688 / 420

Let's proceed to step 4:
When dividing 2688 by 420, we get 6 with a remainder of 168.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 2520 from 2688, we get 168.
Take the next digit (6) from the dividend and append it to 168, then repeat: 1686 / 420

Let's proceed to step 5:
420 can be fit into 1686 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 1680 from 1686, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 420

Let's proceed to step 6:
65 divided by 420 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 640.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 420

Going ahead to step 7:
When dividing 651 by 420, we get 1 with a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 6401.0
Subtract 420 from 651 to get 231.
Fetch the next digit (4) from the dividend, attach it to 231 and continue: 2314 / 420

On to step 8:
The number 420 fits into 2314 5 times, leaving a remainder of 214.
Put 5 as the next digit of the answer. 
Result so far: 64015.0
If we subtract 2100 from 2314, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 9:
2140 divided by 420 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 64015.5
Subtracting 2100 from 2140 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.

Step 10:
When dividing 400 by 420, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 64015.5
If we take 0 away from 400, we end up 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.

Let's proceed to step 11:
420 can be fit into 4000 9 times, resulting in a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 64015.509
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.

Step 12:
2200 divided by 420 is 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 64015.5095
Subtract 2100 from 2200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
1000 divided by 420 is 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 64015.50952
If we subtract 840 from 1000, we 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.

Advancing to step 14:
The number 420 fits into 1600 3 times, leaving a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 64015.509523
If we take 1260 away from 1600, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
3400 divided by 420 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 64015.5095238
Deduct 3360 from 3400 and we're left 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.

Let's proceed to step 16:
When dividing 400 by 420, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 64015.5095238
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 64015.5095238 with a balance of 4e-07.
