We look at the division of 51836457 by 388 
We want to figure out the number of times 51836457 can be divided by 388.

Step 1:
When dividing 5 by 388, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 388

Step 2:
When dividing 51 by 388, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 388

Going ahead to step 3:
The number 388 fits into 518 1 times, leaving a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 388 from 518 and we're left with 130.
Append the next digit (3) from the dividend to 130 and continue with: 1303 / 388

Advancing to step 4:
388 can be fit into 1303 3 times, resulting in a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1164 from 1303 to get 139.
Fetch the next digit (6) from the dividend, attach it to 139 and continue: 1396 / 388

Moving on to step 5:
388 goes into 1396 3 times with a remainder of 232.
The next digit of our result is 3. 
Result so far: 133.0
If we take 1164 away from 1396, we end up with 232.
Fetch the next digit (4) from the dividend, attach it to 232 and continue: 2324 / 388

Moving on to step 6:
388 can be fit into 2324 5 times, resulting in a remainder of 384.
Record the quotient 5 as the next digit in the result. 
Result so far: 1335.0
If we take 1940 away from 2324, we end up with 384.
Take the next digit (5) from the dividend and append it to 384, then repeat: 3845 / 388

Step 7:
388 goes into 3845 9 times with a remainder of 353.
Write down 9 as next digit of the result. 
Result so far: 13359.0
Subtracting 3492 from 3845 leaves us with 353.
Grab the next digit (7) from the dividend, add it to 353, then carry on: 3537 / 388

Going ahead to step 8:
3537 divided by 388 is 9 with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 133599.0
Deduct 3492 from 3537 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 388, we get 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 133599.1
Subtract 388 from 450 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
If we divide 620 by 388, we get 1 and a remainder of 232.
Use 1 as the next digit of our solution. 
Result so far: 133599.11
Subtract 388 from 620 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 133599.11 with a remaining 0.232.
