We look at the division of 2889122 by 391 
We want to figure out the number of times 2889122 can be divided by 391.

Going ahead to step 1:
2 divided by 391 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 391

On to step 2:
28 divided by 391 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 391

Step 3:
The number 391 fits into 288 0 times, leaving a remainder of 288.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 288, we end up with 288.
Append the next digit (9) from the dividend to 288 and continue with: 2889 / 391

Moving on to step 4:
The number 391 fits into 2889 7 times, leaving a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 2737 away from 2889, we end up with 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 391

On to step 5:
If we divide 1521 by 391, we get 3 and a remainder of 348.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 1173 from 1521 leaves us with 348.
Bring next digit (2) of the dividend behind the 348 and repeat the process: 3482 / 391

On to step 6:
The number 391 fits into 3482 8 times, leaving a remainder of 354.
Record the quotient 8 as the next digit in the result. 
Result so far: 738.0
Subtract 3128 from 3482 to get 354.
Bring next digit (2) of the dividend behind the 354 and repeat the process: 3542 / 391

Advancing to step 7:
If we divide 3542 by 391, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 7389.0
If we take 3519 away from 3542, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
The number 391 fits into 230 0 times, leaving a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 7389.0
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 9:
The number 391 fits into 2300 5 times, leaving a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 7389.05
If we take 1955 away from 2300, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 10:
391 can be fit into 3450 8 times, resulting in a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 7389.058
If we take 3128 away from 3450, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 11:
The number 391 fits into 3220 8 times, leaving a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 7389.0588
If we subtract 3128 from 3220, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 7389.0588, with a leftover of 0.00092.
