We're dividing 51687099 by 358 
We want to figure out the number of times 51687099 can be divided by 358.

Step 1:
The number 358 fits into 5 0 times, leaving 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.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 358

On to step 2:
358 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 358

On to step 3:
358 can be fit into 516 1 times, resulting in a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 358 from 516 to get 158.
Include the next digit (8) from the dividend after 158, then repeat: 1588 / 358

On to step 4:
358 goes into 1588 4 times with a remainder of 156.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1432 from 1588 to get 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 358

On to step 5:
1567 divided by 358 is 4 with a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 1432 from 1567, we get 135.
Grab the next digit (0) from the dividend, add it to 135, then carry on: 1350 / 358

Moving on to step 6:
358 goes into 1350 3 times with a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 1443.0
If we subtract 1074 from 1350, we get 276.
Fetch the next digit (9) from the dividend, attach it to 276 and continue: 2769 / 358

Moving on to step 7:
The number 358 fits into 2769 7 times, leaving a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 14437.0
Subtracting 2506 from 2769 leaves us with 263.
Grab the next digit (9) from the dividend, add it to 263, then carry on: 2639 / 358

Moving on to step 8:
The number 358 fits into 2639 7 times, leaving a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 144377.0
If we subtract 2506 from 2639, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 9:
358 can be fit into 1330 3 times, resulting in a remainder of 256.
The number 3 becomes the next digit in our result. 
Result so far: 144377.3
Subtract 1074 from 1330 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 10:
When dividing 2560 by 358, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 144377.37
The remainder is 54 after subtracting 2506 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
When dividing 540 by 358, we get 1 with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 144377.371
The remainder is 182 after subtracting 358 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 12:
When dividing 1820 by 358, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 144377.3715
Subtract 1790 from 1820 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
358 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 144377.3715
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
When dividing 3000 by 358, we get 8 with a remainder of 136.
The next digit of our result is 8. 
Result so far: 144377.371508
The remainder is 136 after subtracting 2864 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 15:
358 can be fit into 1360 3 times, resulting in a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 144377.3715083
Deduct 1074 from 1360 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 16:
The number 358 fits into 2860 7 times, leaving a remainder of 354.
Use 7 as the next digit of our solution. 
Result so far: 144377.37150837
Deduct 2506 from 2860 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 144377.37150837 with a remaining 3.54e-07.
