45438931 ÷ 147 
We want to divide 45438931 by 147.

On to step 1:
147 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 147

Going ahead to step 2:
147 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 147

Advancing to step 3:
The number 147 fits into 454 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 441 from 454, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 147

Going ahead to step 4:
133 divided by 147 is 0 with a remainder of 133.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 133, we end up with 133.
Append the next digit (8) from the dividend to 133 and continue with: 1338 / 147

Advancing to step 5:
The number 147 fits into 1338 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 309.0
If we take 1323 away from 1338, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 147

Moving on to step 6:
147 can be fit into 159 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 3091.0
The remainder is 12 after subtracting 147 from 159.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 147

Let's proceed to step 7:
147 can be fit into 123 0 times, resulting in a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 30910.0
Deduct 0 from 123 and we're left with 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 147

Let's proceed to step 8:
147 goes into 1231 8 times with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 309108.0
If we take 1176 away from 1231, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
550 divided by 147 is 3 with a remainder of 109.
The next digit of our result is 3. 
Result so far: 309108.3
If we take 441 away from 550, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 10:
If we divide 1090 by 147, we get 7 and a remainder of 61.
The next digit of our result is 7. 
Result so far: 309108.37
If we take 1029 away from 1090, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
When dividing 610 by 147, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 309108.374
If we take 588 away from 610, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
When dividing 220 by 147, we get 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 309108.3741
Subtracting 147 from 220 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 13:
147 goes into 730 4 times with a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 309108.37414
If we subtract 588 from 730, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 14:
1420 divided by 147 is 9 with a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 309108.374149
Deduct 1323 from 1420 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 15:
147 goes into 970 6 times with a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 309108.3741496
Deduct 882 from 970 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
The number 147 fits into 880 5 times, leaving a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 309108.37414965
Subtract 735 from 880 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 309108.37414965 and a remainder of 1.45e-07.
