20058173 ÷ 138 
Our goal is to divide 20058173 by 138.

On to step 1:
The number 138 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 138

Moving on to step 2:
If we divide 20 by 138, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 138

Moving on to step 3:
The number 138 fits into 200 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 138 from 200 to get 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 138

Going ahead to step 4:
When dividing 625 by 138, we get 4 with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 552 from 625, we get 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 138

Moving on to step 5:
738 divided by 138 is 5 with a remainder of 48.
The next digit of our result is 5. 
Result so far: 145.0
If we subtract 690 from 738, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 138

Step 6:
138 goes into 481 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 1453.0
The remainder is 67 after subtracting 414 from 481.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 138

On to step 7:
If we divide 677 by 138, we get 4 and a remainder of 125.
Write down 4 as next digit of the result. 
Result so far: 14534.0
If we subtract 552 from 677, we get 125.
Grab the next digit (3) from the dividend, add it to 125, then carry on: 1253 / 138

On to step 8:
1253 divided by 138 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 145349.0
Deduct 1242 from 1253 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
If we divide 110 by 138, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 145349.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
The number 138 fits into 1100 7 times, leaving a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 145349.07
Subtracting 966 from 1100 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 11:
138 can be fit into 1340 9 times, resulting in a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 145349.079
Deduct 1242 from 1340 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
138 goes into 980 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 145349.0797
If we subtract 966 from 980, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
The number 138 fits into 140 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 145349.07971
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
20 divided by 138 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 145349.07971
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
200 divided by 138 is 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 145349.0797101
The remainder is 62 after subtracting 138 from 200.
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 16:
The number 138 fits into 620 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 145349.07971014
Subtracting 552 from 620 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 145349.07971014 with a remaining 6.8e-08.
