We're dividing 51228530 by 361 
We want to figure out the number of times 51228530 can be divided by 361.

Going ahead to step 1:
When dividing 5 by 361, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 361

Advancing to step 2:
51 divided by 361 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 361

Step 3:
If we divide 512 by 361, we get 1 and a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 361 from 512 leaves us with 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 361

Moving on to step 4:
1512 divided by 361 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1444 from 1512 and we're left with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 361

Going ahead to step 5:
If we divide 688 by 361, we get 1 and a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 141.0
Subtracting 361 from 688 leaves us with 327.
Include the next digit (5) from the dividend after 327, then repeat: 3275 / 361

Step 6:
When dividing 3275 by 361, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 1419.0
Subtract 3249 from 3275 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 361

Advancing to step 7:
If we divide 263 by 361, we get 0 and a remainder of 263.
The next digit of our result is 0. 
Result so far: 14190.0
Subtracting 0 from 263 leaves us with 263.
Bring next digit (0) of the dividend behind the 263 and repeat the process: 2630 / 361

Step 8:
361 can be fit into 2630 7 times, resulting in a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 141907.0
If we subtract 2527 from 2630, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
The number 361 fits into 1030 2 times, leaving a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 141907.2
Subtract 722 from 1030 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 10:
3080 divided by 361 is 8 with a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 141907.28
Subtracting 2888 from 3080 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 11:
When dividing 1920 by 361, we get 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 141907.285
Deduct 1805 from 1920 and we're left 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.

Advancing to step 12:
361 goes into 1150 3 times with a remainder of 67.
The next digit of our result is 3. 
Result so far: 141907.2853
If we subtract 1083 from 1150, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 13:
When dividing 670 by 361, we get 1 with a remainder of 309.
The next digit of our result is 1. 
Result so far: 141907.28531
If we take 361 away from 670, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 14:
If we divide 3090 by 361, we get 8 and a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 141907.285318
Subtracting 2888 from 3090 leaves us 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 15:
361 can be fit into 2020 5 times, resulting in a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 141907.2853185
The remainder is 215 after subtracting 1805 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 16:
The number 361 fits into 2150 5 times, leaving a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 141907.28531855
Deduct 1805 from 2150 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Our division results in 141907.28531855 with a remaining 3.45e-07.
