Let's divide 78885517 by 490
We want to figure out the number of times 78885517 can be divided by 490.

Let's proceed to step 1:
490 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 490

Moving on to step 2:
490 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 490

Step 3:
When dividing 788 by 490, we get 1 with a remainder of 298.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 490 away from 788, we end up with 298.
Take the next digit (8) from the dividend and append it to 298, then repeat: 2988 / 490

Going ahead to step 4:
When dividing 2988 by 490, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 2940 from 2988 leaves us with 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 490

Step 5:
The number 490 fits into 485 0 times, leaving a remainder of 485.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
If we subtract 0 from 485, we get 485.
Take the next digit (5) from the dividend and append it to 485, then repeat: 4855 / 490

Moving on to step 6:
4855 divided by 490 is 9 with a remainder of 445.
The next digit of our result is 9. 
Result so far: 1609.0
Subtract 4410 from 4855 to get 445.
Include the next digit (1) from the dividend after 445, then repeat: 4451 / 490

Advancing to step 7:
490 goes into 4451 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 16099.0
If we take 4410 away from 4451, we end up with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 490

Going ahead to step 8:
If we divide 417 by 490, we get 0 and a remainder of 417.
Use 0 as the next digit of our solution. 
Result so far: 160990.0
Deduct 0 from 417 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Let's proceed to step 9:
490 goes into 4170 8 times with a remainder of 250.
The number 8 becomes the next digit in our result. 
Result so far: 160990.8
If we take 3920 away from 4170, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
When dividing 2500 by 490, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 160990.85
Subtract 2450 from 2500 to 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.

Moving on to step 11:
500 divided by 490 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 160990.851
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
490 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 160990.851
The remainder is 100 after subtracting 0 from 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 490 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 160990.85102
If we take 980 away from 1000, 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.

Let's proceed to step 14:
When dividing 200 by 490, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 160990.85102
Deduct 0 from 200 and we're left 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.

Going ahead to step 15:
490 goes into 2000 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 160990.8510204
If we subtract 1960 from 2000, we get 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:
If we divide 400 by 490, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 160990.8510204
If we subtract 0 from 400, we 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.

After the division, we end up with 160990.8510204 and a remainder of 4e-07.
