We're dividing 86980286 by 145 
We want to divide 86980286 by 145.

Advancing to step 1:
8 divided by 145 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 145

Step 2:
The number 145 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 145

Moving on to step 3:
145 can be fit into 869 5 times, resulting in a remainder of 144.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 725 from 869 leaves us with 144.
Grab the next digit (8) from the dividend, add it to 144, then carry on: 1448 / 145

Advancing to step 4:
When dividing 1448 by 145, we get 9 with a remainder of 143.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 1305 from 1448 leaves us with 143.
Include the next digit (0) from the dividend after 143, then repeat: 1430 / 145

Moving on to step 5:
If we divide 1430 by 145, we get 9 and a remainder of 125.
Use 9 as the next digit of our solution. 
Result so far: 599.0
Deduct 1305 from 1430 and we're left with 125.
Fetch the next digit (2) from the dividend, attach it to 125 and continue: 1252 / 145

Step 6:
The number 145 fits into 1252 8 times, leaving a remainder of 92.
The next digit of our result is 8. 
Result so far: 5998.0
Subtract 1160 from 1252 to get 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 145

Let's proceed to step 7:
When dividing 928 by 145, we get 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 59986.0
Deduct 870 from 928 and we're left with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 145

Advancing to step 8:
If we divide 586 by 145, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 599864.0
Subtracting 580 from 586 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 145 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 599864.0
If we take 0 away from 60, we end up 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.

Let's proceed to step 10:
The number 145 fits into 600 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 599864.04
Subtracting 580 from 600 leaves us 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.

Advancing to step 11:
The number 145 fits into 200 1 times, leaving a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 599864.041
The remainder is 55 after subtracting 145 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
If we divide 550 by 145, we get 3 and a remainder of 115.
The next digit of our result is 3. 
Result so far: 599864.0413
The remainder is 115 after subtracting 435 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 13:
145 goes into 1150 7 times with a remainder of 135.
The number 7 becomes the next digit in our result. 
Result so far: 599864.04137
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.

Advancing to step 14:
When dividing 1350 by 145, we get 9 with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 599864.041379
Subtract 1305 from 1350 to 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.

Going ahead to step 15:
145 can be fit into 450 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 599864.0413793
Subtracting 435 from 450 leaves us 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.

Going ahead to step 16:
145 goes into 150 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 599864.04137931
Subtract 145 from 150 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 599864.04137931, and the remainder is 5e-09.
