We divide 4088021 by 415
We want to figure out the number of times 4088021 can be divided by 415.

Moving on to step 1:
415 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 415

Step 2:
415 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 415

Moving on to step 3:
408 divided by 415 is 0 with a remainder of 408.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 408, we end up with 408.
Fetch the next digit (8) from the dividend, attach it to 408 and continue: 4088 / 415

Let's proceed to step 4:
If we divide 4088 by 415, we get 9 and a remainder of 353.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 3735 from 4088 and we're left with 353.
Fetch the next digit (0) from the dividend, attach it to 353 and continue: 3530 / 415

On to step 5:
415 can be fit into 3530 8 times, resulting in a remainder of 210.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 3320 from 3530 and we're left with 210.
Append the next digit (2) from the dividend to 210 and continue with: 2102 / 415

Moving on to step 6:
415 goes into 2102 5 times with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 985.0
If we take 2075 away from 2102, we end up with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 415

Let's proceed to step 7:
415 goes into 271 0 times with a remainder of 271.
Use 0 as the next digit of our solution. 
Result so far: 9850.0
Subtracting 0 from 271 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 8:
415 goes into 2710 6 times with a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 9850.6
Deduct 2490 from 2710 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:
The number 415 fits into 2200 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 9850.65
The remainder is 125 after subtracting 2075 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
1250 divided by 415 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 9850.653
If we take 1245 away from 1250, we end up 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 11:
415 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 9850.653
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 415, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 9850.65301
If we take 415 away from 500, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
850 divided by 415 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 9850.653012
Subtracting 830 from 850 leaves us 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.

On to step 14:
When dividing 200 by 415, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 9850.653012
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 15:
The number 415 fits into 2000 4 times, leaving a remainder of 340.
The next digit of our result is 4. 
Result so far: 9850.65301204
The remainder is 340 after subtracting 1660 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 9850.65301204, with a leftover of 3.4e-07.
