We look at the division of 7860370 by 889 
Our goal is to divide 7860370 by 889.

On to step 1:
The number 889 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 889

Moving on to step 2:
The number 889 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 889

Advancing to step 3:
The number 889 fits into 786 0 times, leaving a remainder of 786.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 786, we get 786.
Include the next digit (0) from the dividend after 786, then repeat: 7860 / 889

Let's proceed to step 4:
If we divide 7860 by 889, we get 8 and a remainder of 748.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7112 from 7860 and we're left with 748.
Fetch the next digit (3) from the dividend, attach it to 748 and continue: 7483 / 889

Advancing to step 5:
The number 889 fits into 7483 8 times, leaving a remainder of 371.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 7112 from 7483 leaves us with 371.
Include the next digit (7) from the dividend after 371, then repeat: 3717 / 889

Going ahead to step 6:
889 can be fit into 3717 4 times, resulting in a remainder of 161.
The next digit of our result is 4. 
Result so far: 884.0
Subtracting 3556 from 3717 leaves us with 161.
Append the next digit (0) from the dividend to 161 and continue with: 1610 / 889

Advancing to step 7:
When dividing 1610 by 889, we get 1 with a remainder of 721.
Write down 1 as next digit of the result. 
Result so far: 8841.0
If we take 889 away from 1610, we end up with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

On to step 8:
889 goes into 7210 8 times with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 8841.8
Subtracting 7112 from 7210 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 9:
The number 889 fits into 980 1 times, leaving a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 8841.81
The remainder is 91 after subtracting 889 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
889 goes into 910 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 8841.811
Subtract 889 from 910 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 8841.811 with a remaining 0.0021.
