We're dividing 86889399 by 372 
We want to figure out the number of times 86889399 can be divided by 372.

Going ahead to step 1:
When dividing 8 by 372, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 372

Moving on to step 2:
372 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 372

Let's proceed to step 3:
372 goes into 868 2 times with a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 744 from 868 leaves us with 124.
Bring next digit (8) of the dividend behind the 124 and repeat the process: 1248 / 372

Step 4:
372 can be fit into 1248 3 times, resulting in a remainder of 132.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 1116 from 1248 to get 132.
Append the next digit (9) from the dividend to 132 and continue with: 1329 / 372

Let's proceed to step 5:
When dividing 1329 by 372, we get 3 with a remainder of 213.
The next digit of our result is 3. 
Result so far: 233.0
If we take 1116 away from 1329, we end up with 213.
Grab the next digit (3) from the dividend, add it to 213, then carry on: 2133 / 372

Let's proceed to step 6:
2133 divided by 372 is 5 with a remainder of 273.
Record the quotient 5 as the next digit in the result. 
Result so far: 2335.0
Subtract 1860 from 2133 to get 273.
Grab the next digit (9) from the dividend, add it to 273, then carry on: 2739 / 372

Going ahead to step 7:
372 goes into 2739 7 times with a remainder of 135.
The next digit of our result is 7. 
Result so far: 23357.0
Subtract 2604 from 2739 to get 135.
Take the next digit (9) from the dividend and append it to 135, then repeat: 1359 / 372

On to step 8:
372 goes into 1359 3 times with a remainder of 243.
The next digit of our result is 3. 
Result so far: 233573.0
Deduct 1116 from 1359 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 9:
If we divide 2430 by 372, we get 6 and a remainder of 198.
The next digit of our result is 6. 
Result so far: 233573.6
If we subtract 2232 from 2430, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
372 goes into 1980 5 times with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 233573.65
Subtract 1860 from 1980 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
When dividing 1200 by 372, we get 3 with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 233573.653
If we take 1116 away from 1200, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
The number 372 fits into 840 2 times, leaving a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 233573.6532
The remainder is 96 after subtracting 744 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
When dividing 960 by 372, we get 2 with a remainder of 216.
The next digit of our result is 2. 
Result so far: 233573.65322
The remainder is 216 after subtracting 744 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 233573.65322 and a remainder of 0.000216.
