We look at the division of 51058734 by 145 
We want to divide 51058734 by 145.

Moving on to step 1:
5 divided by 145 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 145

Moving on to step 2:
145 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 145

Let's proceed to step 3:
If we divide 510 by 145, we get 3 and a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 435 from 510 to get 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 145

Going ahead to step 4:
When dividing 755 by 145, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 725 from 755 and we're left with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 145

Going ahead to step 5:
The number 145 fits into 308 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 352.0
Subtracting 290 from 308 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 145

On to step 6:
The number 145 fits into 187 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 3521.0
Deduct 145 from 187 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 145

Let's proceed to step 7:
If we divide 423 by 145, we get 2 and a remainder of 133.
Write down 2 as next digit of the result. 
Result so far: 35212.0
Subtract 290 from 423 to get 133.
Take the next digit (4) from the dividend and append it to 133, then repeat: 1334 / 145

On to step 8:
145 goes into 1334 9 times with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 352129.0
Subtracting 1305 from 1334 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
145 goes into 290 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 352129.2
If we subtract 290 from 290, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 145, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 352129.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 145 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 352129.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 352129.2, with a leftover of 0.0.
