51278902 divided by 359 
Our goal is to divide 51278902 by 359.

On to step 1:
The number 359 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 359

Step 2:
359 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 359

Moving on to step 3:
359 goes into 512 1 times with a remainder of 153.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 153 after subtracting 359 from 512.
Append the next digit (7) from the dividend to 153 and continue with: 1537 / 359

On to step 4:
1537 divided by 359 is 4 with a remainder of 101.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1436 from 1537 to get 101.
Bring next digit (8) of the dividend behind the 101 and repeat the process: 1018 / 359

Going ahead to step 5:
If we divide 1018 by 359, we get 2 and a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we take 718 away from 1018, we end up with 300.
Fetch the next digit (9) from the dividend, attach it to 300 and continue: 3009 / 359

Going ahead to step 6:
3009 divided by 359 is 8 with a remainder of 137.
Use 8 as the next digit of our solution. 
Result so far: 1428.0
Deduct 2872 from 3009 and we're left with 137.
Include the next digit (0) from the dividend after 137, then repeat: 1370 / 359

Step 7:
When dividing 1370 by 359, we get 3 with a remainder of 293.
Record the quotient 3 as the next digit in the result. 
Result so far: 14283.0
Subtracting 1077 from 1370 leaves us with 293.
Append the next digit (2) from the dividend to 293 and continue with: 2932 / 359

Let's proceed to step 8:
359 goes into 2932 8 times with a remainder of 60.
The next digit of our result is 8. 
Result so far: 142838.0
The remainder is 60 after subtracting 2872 from 2932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
600 divided by 359 is 1 with a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 142838.1
If we take 359 away from 600, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 10:
The number 359 fits into 2410 6 times, leaving a remainder of 256.
The number 6 becomes the next digit in our result. 
Result so far: 142838.16
If we take 2154 away from 2410, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
359 goes into 2560 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 142838.167
Subtract 2513 from 2560 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
The number 359 fits into 470 1 times, leaving a remainder of 111.
The next digit of our result is 1. 
Result so far: 142838.1671
Subtract 359 from 470 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 13:
359 can be fit into 1110 3 times, resulting in a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 142838.16713
If we take 1077 away from 1110, we end up 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.

Advancing to step 14:
If we divide 330 by 359, we get 0 and a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 142838.16713
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 15:
When dividing 3300 by 359, we get 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 142838.1671309
Deduct 3231 from 3300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 16:
When dividing 690 by 359, we get 1 with a remainder of 331.
Use 1 as the next digit of our solution. 
Result so far: 142838.16713091
If we take 359 away from 690, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final outcome is 142838.16713091, with a leftover of 3.31e-07.
