55638331 divided by 138 
We want to figure out the number of times 55638331 can be divided by 138.

Going ahead to step 1:
If we divide 5 by 138, we get 0 and 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 (5) from the dividend, add it to 5, then carry on: 55 / 138

Let's proceed to step 2:
138 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 138

Let's proceed to step 3:
If we divide 556 by 138, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 552 from 556 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 138

Let's proceed to step 4:
If we divide 43 by 138, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 138

Advancing to step 5:
When dividing 438 by 138, we get 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 403.0
If we take 414 away from 438, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 138

On to step 6:
138 can be fit into 243 1 times, resulting in a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 4031.0
Deduct 138 from 243 and we're left with 105.
Include the next digit (3) from the dividend after 105, then repeat: 1053 / 138

Moving on to step 7:
138 goes into 1053 7 times with a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 40317.0
If we take 966 away from 1053, we end up with 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 138

On to step 8:
138 goes into 871 6 times with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 403176.0
If we subtract 828 from 871, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 138, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 403176.3
Subtract 414 from 430 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
138 goes into 160 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 403176.31
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
138 goes into 220 1 times with a remainder of 82.
The next digit of our result is 1. 
Result so far: 403176.311
Subtract 138 from 220 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 403176.311 with a remaining 0.0082.
