Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 146

On to step 2:
When dividing 51 by 146, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 146

Step 3:
If we divide 517 by 146, we get 3 and a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 438 from 517 and we're left with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 146

Moving on to step 4:
146 goes into 793 5 times with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 730 from 793, we get 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 146

Going ahead to step 5:
When dividing 637 by 146, we get 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 354.0
Deduct 584 from 637 and we're left with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 146

Advancing to step 6:
146 goes into 531 3 times with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 3543.0
The remainder is 93 after subtracting 438 from 531.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 146

Let's proceed to step 7:
146 goes into 934 6 times with a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 35436.0
Subtract 876 from 934 to get 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 146

Let's proceed to step 8:
If we divide 589 by 146, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 354364.0
Deduct 584 from 589 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 146 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 354364.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 146, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 354364.03
Subtract 438 from 500 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
The number 146 fits into 620 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 354364.034
Subtract 584 from 620 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
146 goes into 360 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 354364.0342
Subtracting 292 from 360 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
When dividing 680 by 146, we get 4 with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 354364.03424
Subtract 584 from 680 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
146 goes into 960 6 times with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 354364.034246
If we subtract 876 from 960, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 15:
146 goes into 840 5 times with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 354364.0342465
Subtracting 730 from 840 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.

Let's proceed to step 16:
146 goes into 1100 7 times with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 354364.03424657
If we subtract 1022 from 1100, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 354364.03424657 with a remaining 7.8e-08.
