Let's divide 30415473 by 138
We want to figure out the number of times 30415473 can be divided by 138.

On to step 1:
When dividing 3 by 138, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 138

Let's proceed to step 2:
If we divide 30 by 138, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 138

Going ahead to step 3:
304 divided by 138 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 276 from 304 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 138

Advancing to step 4:
281 divided by 138 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 276 from 281 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 138

Going ahead to step 5:
If we divide 55 by 138, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
If we take 0 away from 55, we end up with 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 138

Advancing to step 6:
The number 138 fits into 554 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 2204.0
Deduct 552 from 554 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 138

Let's proceed to step 7:
When dividing 27 by 138, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 22040.0
The remainder is 27 after subtracting 0 from 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 138

Advancing to step 8:
The number 138 fits into 273 1 times, leaving a remainder of 135.
The next digit of our result is 1. 
Result so far: 220401.0
Deduct 138 from 273 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
1350 divided by 138 is 9 with a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 220401.9
If we take 1242 away from 1350, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 10:
When dividing 1080 by 138, we get 7 with a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 220401.97
Deduct 966 from 1080 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 11:
When dividing 1140 by 138, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 220401.978
The remainder is 36 after subtracting 1104 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
When dividing 360 by 138, we get 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 220401.9782
If we subtract 276 from 360, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 13:
138 can be fit into 840 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 220401.97826
Subtract 828 from 840 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
120 divided by 138 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 220401.97826
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
When dividing 1200 by 138, we get 8 with a remainder of 96.
The next digit of our result is 8. 
Result so far: 220401.9782608
If we subtract 1104 from 1200, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
138 goes into 960 6 times with a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 220401.97826086
The remainder is 132 after subtracting 828 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 220401.97826086 with a remaining 1.32e-07.
