We look at the division of 45438611 by 355 
We want to divide 45438611 by 355.

On to step 1:
The number 355 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 355

Moving on to step 2:
355 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 355

On to step 3:
355 can be fit into 454 1 times, resulting in a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 355 from 454 to get 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 355

On to step 4:
355 goes into 993 2 times with a remainder of 283.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 283 after subtracting 710 from 993.
Bring next digit (8) of the dividend behind the 283 and repeat the process: 2838 / 355

On to step 5:
355 goes into 2838 7 times with a remainder of 353.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtracting 2485 from 2838 leaves us with 353.
Append the next digit (6) from the dividend to 353 and continue with: 3536 / 355

Going ahead to step 6:
355 goes into 3536 9 times with a remainder of 341.
Write down 9 as next digit of the result. 
Result so far: 1279.0
Subtracting 3195 from 3536 leaves us with 341.
Include the next digit (1) from the dividend after 341, then repeat: 3411 / 355

Advancing to step 7:
When dividing 3411 by 355, we get 9 with a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 12799.0
If we subtract 3195 from 3411, we get 216.
Append the next digit (1) from the dividend to 216 and continue with: 2161 / 355

Moving on to step 8:
2161 divided by 355 is 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 127996.0
If we subtract 2130 from 2161, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
The number 355 fits into 310 0 times, leaving a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 127996.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
When dividing 3100 by 355, we get 8 with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 127996.08
If we subtract 2840 from 3100, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
When dividing 2600 by 355, we get 7 with a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 127996.087
If we take 2485 away from 2600, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 12:
355 can be fit into 1150 3 times, resulting in a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 127996.0873
Subtracting 1065 from 1150 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 13:
355 goes into 850 2 times with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 127996.08732
Subtracting 710 from 850 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
355 can be fit into 1400 3 times, resulting in a remainder of 335.
Put 3 as the next digit of the answer. 
Result so far: 127996.087323
If we take 1065 away from 1400, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 15:
If we divide 3350 by 355, we get 9 and a remainder of 155.
The number 9 becomes the next digit in our result. 
Result so far: 127996.0873239
Subtracting 3195 from 3350 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 16:
If we divide 1550 by 355, we get 4 and a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 127996.08732394
The remainder is 130 after subtracting 1420 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 127996.08732394 and a remainder of 1.3e-07.
