9904186 divided by 989 
We want to figure out the number of times 9904186 can be divided by 989.

Step 1:
9 divided by 989 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 989

Let's proceed to step 2:
When dividing 99 by 989, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 989

Step 3:
989 goes into 990 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 989 from 990.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 989

Advancing to step 4:
When dividing 14 by 989, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 989

Let's proceed to step 5:
When dividing 141 by 989, we get 0 with a remainder of 141.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 141 to get 141.
Take the next digit (8) from the dividend and append it to 141, then repeat: 1418 / 989

Moving on to step 6:
989 can be fit into 1418 1 times, resulting in a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 1001.0
If we take 989 away from 1418, we end up with 429.
Bring next digit (6) of the dividend behind the 429 and repeat the process: 4296 / 989

Let's proceed to step 7:
The number 989 fits into 4296 4 times, leaving a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 10014.0
If we take 3956 away from 4296, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 8:
989 can be fit into 3400 3 times, resulting in a remainder of 433.
Use 3 as the next digit of our solution. 
Result so far: 10014.3
Subtracting 2967 from 3400 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 9:
4330 divided by 989 is 4 with a remainder of 374.
The number 4 becomes the next digit in our result. 
Result so far: 10014.34
The remainder is 374 after subtracting 3956 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 10:
989 can be fit into 3740 3 times, resulting in a remainder of 773.
The number 3 becomes the next digit in our result. 
Result so far: 10014.343
Subtract 2967 from 3740 to get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Advancing to step 11:
When dividing 7730 by 989, we get 7 with a remainder of 807.
Record the quotient 7 as the next digit in the result. 
Result so far: 10014.3437
If we take 6923 away from 7730, we end up with 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Advancing to step 12:
989 goes into 8070 8 times with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 10014.34378
If we subtract 7912 from 8070, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 13:
989 can be fit into 1580 1 times, resulting in a remainder of 591.
The number 1 becomes the next digit in our result. 
Result so far: 10014.343781
Deduct 989 from 1580 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 14:
When dividing 5910 by 989, we get 5 with a remainder of 965.
The next digit of our result is 5. 
Result so far: 10014.3437815
The remainder is 965 after subtracting 4945 from 5910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

Moving on to step 15:
If we divide 9650 by 989, we get 9 and a remainder of 749.
Record the quotient 9 as the next digit in the result. 
Result so far: 10014.34378159
Subtracting 8901 from 9650 leaves us with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

After the division, we end up with 10014.34378159 and a remainder of 7.49e-07.
