407988 divided by 26 
We want to figure out the number of times 407988 can be divided by 26.

Step 1:
4 divided by 26 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 26

Step 2:
26 goes into 40 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 26 from 40 to get 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 26

Moving on to step 3:
The number 26 fits into 147 5 times, leaving a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 130 from 147 and we're left with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 26

Advancing to step 4:
26 can be fit into 179 6 times, resulting in a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Deduct 156 from 179 and we're left with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 26

Advancing to step 5:
If we divide 238 by 26, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 1569.0
If we take 234 away from 238, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 26

Moving on to step 6:
26 goes into 48 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 15691.0
If we subtract 26 from 48, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
220 divided by 26 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 15691.8
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 26 fits into 120 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 15691.84
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 26, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 15691.846
Subtract 156 from 160 to get 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 10:
40 divided by 26 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 15691.8461
If we take 26 away from 40, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
26 goes into 140 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15691.84615
The remainder is 10 after subtracting 130 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 15691.846153
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
26 can be fit into 220 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 15691.8461538
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
The number 26 fits into 120 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 15691.84615384
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 15691.84615384 with a remainder of 1.6e-08.
