Let's divide 89810321 by 145
We want to figure out the number of times 89810321 can be divided by 145.

Step 1:
145 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 145

Step 2:
If we divide 89 by 145, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 145

On to step 3:
145 can be fit into 898 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 870 from 898, we get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 145

Step 4:
The number 145 fits into 281 1 times, leaving a remainder of 136.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 145 from 281 and we're left with 136.
Fetch the next digit (0) from the dividend, attach it to 136 and continue: 1360 / 145

On to step 5:
145 goes into 1360 9 times with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 619.0
If we take 1305 away from 1360, we end up with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 145

Step 6:
The number 145 fits into 553 3 times, leaving a remainder of 118.
The next digit of our result is 3. 
Result so far: 6193.0
Deduct 435 from 553 and we're left with 118.
Include the next digit (2) from the dividend after 118, then repeat: 1182 / 145

On to step 7:
If we divide 1182 by 145, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 61938.0
If we subtract 1160 from 1182, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 145

Advancing to step 8:
The number 145 fits into 221 1 times, leaving a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 619381.0
The remainder is 76 after subtracting 145 from 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
760 divided by 145 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 619381.5
Subtracting 725 from 760 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
350 divided by 145 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 619381.52
Deduct 290 from 350 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
145 goes into 600 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 619381.524
If we take 580 away from 600, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
When dividing 200 by 145, we get 1 with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 619381.5241
Subtract 145 from 200 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
When dividing 550 by 145, we get 3 with a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 619381.52413
Subtract 435 from 550 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 14:
When dividing 1150 by 145, we get 7 with a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 619381.524137
If we subtract 1015 from 1150, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 15:
145 can be fit into 1350 9 times, resulting in a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 619381.5241379
If we subtract 1305 from 1350, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 16:
145 can be fit into 450 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 619381.52413793
If we take 435 away from 450, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 619381.52413793 with a remaining 1.5e-08.
