45400738 ÷ 349 
Let's see how many times 349 fits into 45400738.

Advancing to step 1:
If we divide 4 by 349, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 349

Moving on to step 2:
45 divided by 349 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 349

On to step 3:
454 divided by 349 is 1 with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 349 from 454 to get 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 349

Step 4:
349 goes into 1050 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1047 from 1050 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 349

Advancing to step 5:
349 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 349

Advancing to step 6:
307 divided by 349 is 0 with a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 1300.0
Subtract 0 from 307 to get 307.
Grab the next digit (3) from the dividend, add it to 307, then carry on: 3073 / 349

On to step 7:
The number 349 fits into 3073 8 times, leaving a remainder of 281.
Put 8 as the next digit of the answer. 
Result so far: 13008.0
If we take 2792 away from 3073, we end up with 281.
Grab the next digit (8) from the dividend, add it to 281, then carry on: 2818 / 349

On to step 8:
349 can be fit into 2818 8 times, resulting in a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 130088.0
If we subtract 2792 from 2818, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
The number 349 fits into 260 0 times, leaving a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 130088.0
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
2600 divided by 349 is 7 with a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 130088.07
If we subtract 2443 from 2600, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 11:
If we divide 1570 by 349, we get 4 and a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 130088.074
Subtract 1396 from 1570 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 12:
When dividing 1740 by 349, we get 4 with a remainder of 344.
Write down 4 as next digit of the result. 
Result so far: 130088.0744
Deduct 1396 from 1740 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The quotient of the division is 130088.0744, and the remainder is 0.00344.
