We look at the division of 3899917 by 291 
We're looking to find how many times 291 goes into 3899917.

On to step 1:
When dividing 3 by 291, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 291

Going ahead to step 2:
291 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 291

Let's proceed to step 3:
If we divide 389 by 291, we get 1 and a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 291 from 389, we get 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 291

Advancing to step 4:
The number 291 fits into 989 3 times, leaving a remainder of 116.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 873 from 989 leaves us with 116.
Take the next digit (9) from the dividend and append it to 116, then repeat: 1169 / 291

Advancing to step 5:
1169 divided by 291 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 134.0
Deduct 1164 from 1169 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 291

Moving on to step 6:
When dividing 51 by 291, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 1340.0
If we take 0 away from 51, we end up with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 291

Step 7:
517 divided by 291 is 1 with a remainder of 226.
Record the quotient 1 as the next digit in the result. 
Result so far: 13401.0
If we take 291 away from 517, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 8:
When dividing 2260 by 291, we get 7 with a remainder of 223.
The next digit of our result is 7. 
Result so far: 13401.7
Subtract 2037 from 2260 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 9:
The number 291 fits into 2230 7 times, leaving a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 13401.77
Subtract 2037 from 2230 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Our division results in 13401.77 with a remaining 0.193.
