51383697 divided by 351 
We want to divide 51383697 by 351.

Let's proceed to step 1:
351 can be fit into 5 0 times, resulting in 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 351

Moving on to step 2:
When dividing 51 by 351, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 351

Moving on to step 3:
If we divide 513 by 351, we get 1 and a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 351 from 513 and we're left with 162.
Take the next digit (8) from the dividend and append it to 162, then repeat: 1628 / 351

Moving on to step 4:
351 can be fit into 1628 4 times, resulting in a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 1404 away from 1628, we end up with 224.
Include the next digit (3) from the dividend after 224, then repeat: 2243 / 351

Going ahead to step 5:
2243 divided by 351 is 6 with a remainder of 137.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
If we subtract 2106 from 2243, we get 137.
Append the next digit (6) from the dividend to 137 and continue with: 1376 / 351

Going ahead to step 6:
351 goes into 1376 3 times with a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 1463.0
Deduct 1053 from 1376 and we're left with 323.
Bring next digit (9) of the dividend behind the 323 and repeat the process: 3239 / 351

On to step 7:
3239 divided by 351 is 9 with a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 14639.0
If we take 3159 away from 3239, we end up with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 351

Step 8:
When dividing 807 by 351, we get 2 with a remainder of 105.
Put 2 as the next digit of the answer. 
Result so far: 146392.0
If we take 702 away from 807, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
If we divide 1050 by 351, we get 2 and a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 146392.2
If we take 702 away from 1050, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 10:
The number 351 fits into 3480 9 times, leaving a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 146392.29
Deduct 3159 from 3480 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 11:
The number 351 fits into 3210 9 times, leaving a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 146392.299
Deduct 3159 from 3210 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 146392.299, with a leftover of 0.0051.
