9912158 divided by 886 
We want to figure out the number of times 9912158 can be divided by 886.

Moving on to step 1:
If we divide 9 by 886, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 886

Let's proceed to step 2:
99 divided by 886 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Bring next digit (1) of the dividend behind the 99 and repeat the process: 991 / 886

Moving on to step 3:
The number 886 fits into 991 1 times, leaving a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 886 from 991 and we're left with 105.
Grab the next digit (2) from the dividend, add it to 105, then carry on: 1052 / 886

Going ahead to step 4:
When dividing 1052 by 886, we get 1 with a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 886 away from 1052, we end up with 166.
Append the next digit (1) from the dividend to 166 and continue with: 1661 / 886

Step 5:
886 can be fit into 1661 1 times, resulting in a remainder of 775.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we take 886 away from 1661, we end up with 775.
Take the next digit (5) from the dividend and append it to 775, then repeat: 7755 / 886

Let's proceed to step 6:
When dividing 7755 by 886, we get 8 with a remainder of 667.
Write down 8 as next digit of the result. 
Result so far: 1118.0
Deduct 7088 from 7755 and we're left with 667.
Grab the next digit (8) from the dividend, add it to 667, then carry on: 6678 / 886

Moving on to step 7:
886 can be fit into 6678 7 times, resulting in a remainder of 476.
Write down 7 as next digit of the result. 
Result so far: 11187.0
If we subtract 6202 from 6678, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 8:
When dividing 4760 by 886, we get 5 with a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 11187.5
Subtracting 4430 from 4760 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 9:
3300 divided by 886 is 3 with a remainder of 642.
Use 3 as the next digit of our solution. 
Result so far: 11187.53
If we take 2658 away from 3300, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 10:
The number 886 fits into 6420 7 times, leaving a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 11187.537
If we subtract 6202 from 6420, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 11:
886 goes into 2180 2 times with a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 11187.5372
If we take 1772 away from 2180, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 12:
4080 divided by 886 is 4 with a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 11187.53724
The remainder is 536 after subtracting 3544 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 13:
The number 886 fits into 5360 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 11187.537246
Deduct 5316 from 5360 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
If we divide 440 by 886, we get 0 and a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 11187.537246
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 15:
886 goes into 4400 4 times with a remainder of 856.
Write down 4 as next digit of the result. 
Result so far: 11187.53724604
Deduct 3544 from 4400 and we're left with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

After the division, we end up with 11187.53724604 and a remainder of 8.56e-07.
