Let's divide 89134478 by 210
Let's see how many times 210 fits into 89134478.

Advancing to step 1:
210 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 210

Going ahead to step 2:
210 can be fit into 89 0 times, resulting in a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 210

Going ahead to step 3:
210 can be fit into 891 4 times, resulting in a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 840 from 891 to get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 210

Going ahead to step 4:
If we divide 513 by 210, we get 2 and a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 420 from 513, we get 93.
Append the next digit (4) from the dividend to 93 and continue with: 934 / 210

Step 5:
210 can be fit into 934 4 times, resulting in a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 424.0
If we take 840 away from 934, we end up with 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 210

On to step 6:
944 divided by 210 is 4 with a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 4244.0
If we take 840 away from 944, we end up with 104.
Grab the next digit (7) from the dividend, add it to 104, then carry on: 1047 / 210

Moving on to step 7:
1047 divided by 210 is 4 with a remainder of 207.
Use 4 as the next digit of our solution. 
Result so far: 42444.0
If we take 840 away from 1047, we end up with 207.
Append the next digit (8) from the dividend to 207 and continue with: 2078 / 210

Step 8:
If we divide 2078 by 210, we get 9 and a remainder of 188.
Put 9 as the next digit of the answer. 
Result so far: 424449.0
Subtract 1890 from 2078 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 9:
When dividing 1880 by 210, we get 8 with a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 424449.8
The remainder is 200 after subtracting 1680 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
When dividing 2000 by 210, we get 9 with a remainder of 110.
The next digit of our result is 9. 
Result so far: 424449.89
If we subtract 1890 from 2000, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 11:
If we divide 1100 by 210, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 424449.895
Deduct 1050 from 1100 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
500 divided by 210 is 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 424449.8952
If we take 420 away from 500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
When dividing 800 by 210, we get 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 424449.89523
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
1700 divided by 210 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 424449.895238
If we subtract 1680 from 1700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
If we divide 200 by 210, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 424449.895238
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
210 goes into 2000 9 times with a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 424449.89523809
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 424449.89523809, with a leftover of 1.1e-07.
