Let's divide 51350074 by 397
We're looking to find how many times 397 goes into 51350074.

On to step 1:
5 divided by 397 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 397

Advancing to step 2:
If we divide 51 by 397, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 397

On to step 3:
When dividing 513 by 397, we get 1 with a remainder of 116.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 116 after subtracting 397 from 513.
Grab the next digit (5) from the dividend, add it to 116, then carry on: 1165 / 397

On to step 4:
397 goes into 1165 2 times with a remainder of 371.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 794 away from 1165, we end up with 371.
Take the next digit (0) from the dividend and append it to 371, then repeat: 3710 / 397

Let's proceed to step 5:
If we divide 3710 by 397, we get 9 and a remainder of 137.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtracting 3573 from 3710 leaves us with 137.
Fetch the next digit (0) from the dividend, attach it to 137 and continue: 1370 / 397

Moving on to step 6:
If we divide 1370 by 397, we get 3 and a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 1293.0
If we take 1191 away from 1370, we end up with 179.
Append the next digit (7) from the dividend to 179 and continue with: 1797 / 397

On to step 7:
The number 397 fits into 1797 4 times, leaving a remainder of 209.
Write down 4 as next digit of the result. 
Result so far: 12934.0
If we subtract 1588 from 1797, we get 209.
Include the next digit (4) from the dividend after 209, then repeat: 2094 / 397

On to step 8:
If we divide 2094 by 397, we get 5 and a remainder of 109.
Record the quotient 5 as the next digit in the result. 
Result so far: 129345.0
Deduct 1985 from 2094 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 9:
When dividing 1090 by 397, we get 2 with a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 129345.2
If we subtract 794 from 1090, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 10:
397 goes into 2960 7 times with a remainder of 181.
The next digit of our result is 7. 
Result so far: 129345.27
If we subtract 2779 from 2960, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 11:
1810 divided by 397 is 4 with a remainder of 222.
The number 4 becomes the next digit in our result. 
Result so far: 129345.274
Subtract 1588 from 1810 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 12:
When dividing 2220 by 397, we get 5 with a remainder of 235.
The next digit of our result is 5. 
Result so far: 129345.2745
If we take 1985 away from 2220, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 13:
397 can be fit into 2350 5 times, resulting in a remainder of 365.
The next digit of our result is 5. 
Result so far: 129345.27455
Subtracting 1985 from 2350 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

After the division, we end up with 129345.27455 and a remainder of 0.000365.
