We're dividing 89477728 by 210 
We want to figure out the number of times 89477728 can be divided by 210.

Going ahead to step 1:
When dividing 8 by 210, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 210

Moving on to step 2:
The number 210 fits into 89 0 times, leaving a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 210

Let's proceed to step 3:
210 goes into 894 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 840 from 894 to get 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 210

On to step 4:
210 goes into 547 2 times with a remainder of 127.
The next digit of our result is 2. 
Result so far: 42.0
If we take 420 away from 547, we end up with 127.
Include the next digit (7) from the dividend after 127, then repeat: 1277 / 210

On to step 5:
The number 210 fits into 1277 6 times, leaving a remainder of 17.
The next digit of our result is 6. 
Result so far: 426.0
The remainder is 17 after subtracting 1260 from 1277.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 210

On to step 6:
210 goes into 177 0 times with a remainder of 177.
Use 0 as the next digit of our solution. 
Result so far: 4260.0
The remainder is 177 after subtracting 0 from 177.
Take the next digit (2) from the dividend and append it to 177, then repeat: 1772 / 210

Moving on to step 7:
1772 divided by 210 is 8 with a remainder of 92.
The next digit of our result is 8. 
Result so far: 42608.0
Subtracting 1680 from 1772 leaves us with 92.
Take the next digit (8) from the dividend and append it to 92, then repeat: 928 / 210

Let's proceed to step 8:
210 goes into 928 4 times with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 426084.0
Deduct 840 from 928 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
The number 210 fits into 880 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 426084.4
Subtract 840 from 880 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
210 goes into 400 1 times with a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 426084.41
If we subtract 210 from 400, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
If we divide 1900 by 210, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 426084.419
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
100 divided by 210 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 426084.419
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
When dividing 1000 by 210, we get 4 with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 426084.41904
Subtract 840 from 1000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
If we divide 1600 by 210, we get 7 and a remainder of 130.
The next digit of our result is 7. 
Result so far: 426084.419047
If we subtract 1470 from 1600, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 15:
210 goes into 1300 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 426084.4190476
The remainder is 40 after subtracting 1260 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
If we divide 400 by 210, we get 1 and a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 426084.41904761
Deduct 210 from 400 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

In conclusion, the division gives 426084.41904761 with a balance of 1.9e-07.
