We divide 86774231 by 145
We want to figure out the number of times 86774231 can be divided by 145.

Let's proceed to step 1:
When dividing 8 by 145, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 145

On to step 2:
145 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 145

Going ahead to step 3:
When dividing 867 by 145, we get 5 with a remainder of 142.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 725 from 867 leaves us with 142.
Bring next digit (7) of the dividend behind the 142 and repeat the process: 1427 / 145

Moving on to step 4:
145 can be fit into 1427 9 times, resulting in a remainder of 122.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtracting 1305 from 1427 leaves us with 122.
Append the next digit (4) from the dividend to 122 and continue with: 1224 / 145

Step 5:
145 can be fit into 1224 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 598.0
Subtracting 1160 from 1224 leaves us with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 145

Advancing to step 6:
The number 145 fits into 642 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 5984.0
If we take 580 away from 642, we end up with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 145

On to step 7:
145 goes into 623 4 times with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 59844.0
Subtracting 580 from 623 leaves us with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 145

Going ahead to step 8:
431 divided by 145 is 2 with a remainder of 141.
Put 2 as the next digit of the answer. 
Result so far: 598442.0
Subtracting 290 from 431 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
The number 145 fits into 1410 9 times, leaving a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 598442.9
Subtract 1305 from 1410 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
The number 145 fits into 1050 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 598442.97
If we take 1015 away from 1050, we end up 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.

Going ahead to step 11:
When dividing 350 by 145, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 598442.972
Subtract 290 from 350 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 145, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 598442.9724
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.

Moving on to step 13:
145 can be fit into 200 1 times, resulting in a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 598442.97241
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 14:
145 can be fit into 550 3 times, resulting in a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 598442.972413
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.

On to step 15:
1150 divided by 145 is 7 with a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 598442.9724137
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 16:
When dividing 1350 by 145, we get 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 598442.97241379
If we take 1305 away from 1350, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 598442.97241379, with a leftover of 4.5e-08.
