We're dividing 51951356 by 301 
We want to figure out the number of times 51951356 can be divided by 301.

Step 1:
When dividing 5 by 301, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 301

Advancing to step 2:
The number 301 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 301

Moving on to step 3:
If we divide 519 by 301, we get 1 and a remainder of 218.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 218 after subtracting 301 from 519.
Bring next digit (5) of the dividend behind the 218 and repeat the process: 2185 / 301

Step 4:
The number 301 fits into 2185 7 times, leaving a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 2107 away from 2185, we end up with 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 301

On to step 5:
If we divide 781 by 301, we get 2 and a remainder of 179.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we take 602 away from 781, we end up with 179.
Append the next digit (3) from the dividend to 179 and continue with: 1793 / 301

Advancing to step 6:
When dividing 1793 by 301, we get 5 with a remainder of 288.
Write down 5 as next digit of the result. 
Result so far: 1725.0
Subtracting 1505 from 1793 leaves us with 288.
Grab the next digit (5) from the dividend, add it to 288, then carry on: 2885 / 301

On to step 7:
2885 divided by 301 is 9 with a remainder of 176.
Put 9 as the next digit of the answer. 
Result so far: 17259.0
Deduct 2709 from 2885 and we're left with 176.
Append the next digit (6) from the dividend to 176 and continue with: 1766 / 301

Step 8:
301 goes into 1766 5 times with a remainder of 261.
Put 5 as the next digit of the answer. 
Result so far: 172595.0
Subtracting 1505 from 1766 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 9:
301 goes into 2610 8 times with a remainder of 202.
The number 8 becomes the next digit in our result. 
Result so far: 172595.8
Deduct 2408 from 2610 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
When dividing 2020 by 301, we get 6 with a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 172595.86
If we subtract 1806 from 2020, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
The number 301 fits into 2140 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 172595.867
Subtracting 2107 from 2140 leaves us 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.

Moving on to step 12:
301 goes into 330 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 172595.8671
If we take 301 away from 330, we end up 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 13:
301 can be fit into 290 0 times, resulting in a remainder of 290.
The next digit of our result is 0. 
Result so far: 172595.8671
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 14:
301 can be fit into 2900 9 times, resulting in a remainder of 191.
The number 9 becomes the next digit in our result. 
Result so far: 172595.867109
The remainder is 191 after subtracting 2709 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 15:
301 goes into 1910 6 times with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 172595.8671096
Deduct 1806 from 1910 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 16:
301 can be fit into 1040 3 times, resulting in a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 172595.86710963
If we take 903 away from 1040, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 172595.86710963, with a leftover of 1.37e-07.
