We look at the division of 51078870 by 147 
We want to figure out the number of times 51078870 can be divided by 147.

Going ahead to step 1:
147 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 147

Step 2:
51 divided by 147 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 147

Step 3:
If we divide 510 by 147, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 441 from 510 to get 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 147

Going ahead to step 4:
When dividing 697 by 147, we get 4 with a remainder of 109.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 588 from 697 leaves us with 109.
Bring next digit (8) of the dividend behind the 109 and repeat the process: 1098 / 147

Going ahead to step 5:
The number 147 fits into 1098 7 times, leaving a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 347.0
Deduct 1029 from 1098 and we're left with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 147

Let's proceed to step 6:
The number 147 fits into 698 4 times, leaving a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 3474.0
If we subtract 588 from 698, we get 110.
Grab the next digit (7) from the dividend, add it to 110, then carry on: 1107 / 147

On to step 7:
147 can be fit into 1107 7 times, resulting in a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 34747.0
If we subtract 1029 from 1107, we get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 147

Going ahead to step 8:
147 goes into 780 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 347475.0
If we take 735 away from 780, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
When dividing 450 by 147, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 347475.3
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
The number 147 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 347475.3
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
147 can be fit into 900 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 347475.306
Subtract 882 from 900 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
147 can be fit into 180 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 347475.3061
Deduct 147 from 180 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
147 goes into 330 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 347475.30612
Subtract 294 from 330 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.

Step 14:
147 can be fit into 360 2 times, resulting in a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 347475.306122
Subtracting 294 from 360 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 347475.306122, with a leftover of 6.6e-06.
