We look at the division of 20260398 by 215 
We want to figure out the number of times 20260398 can be divided by 215.

On to step 1:
2 divided by 215 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 215

Going ahead to step 2:
215 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 215

Going ahead to step 3:
202 divided by 215 is 0 with a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 202 to get 202.
Append the next digit (6) from the dividend to 202 and continue with: 2026 / 215

Going ahead to step 4:
If we divide 2026 by 215, we get 9 and a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 91 after subtracting 1935 from 2026.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 215

Moving on to step 5:
The number 215 fits into 910 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtract 860 from 910 to get 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 215

Moving on to step 6:
When dividing 503 by 215, we get 2 with a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 942.0
If we subtract 430 from 503, we get 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 215

Step 7:
215 goes into 739 3 times with a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 9423.0
If we subtract 645 from 739, we get 94.
Take the next digit (8) from the dividend and append it to 94, then repeat: 948 / 215

Step 8:
If we divide 948 by 215, we get 4 and a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 94234.0
The remainder is 88 after subtracting 860 from 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
The number 215 fits into 880 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 94234.4
If we take 860 away from 880, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
215 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 94234.4
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
If we divide 2000 by 215, we get 9 and a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 94234.409
Deduct 1935 from 2000 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
If we divide 650 by 215, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 94234.4093
Deduct 645 from 650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
The number 215 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 94234.4093
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 215, we get 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 94234.409302
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
700 divided by 215 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 94234.4093023
Deduct 645 from 700 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 16:
215 can be fit into 550 2 times, resulting in a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 94234.40930232
If we subtract 430 from 550, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 94234.40930232, with a leftover of 1.2e-07.
