We look at the division of 29621258 by 138 
Our goal is to divide 29621258 by 138.

On to step 1:
The number 138 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 138

Going ahead to step 2:
138 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 138

Advancing to step 3:
When dividing 296 by 138, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 276 from 296 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 138

Moving on to step 4:
138 can be fit into 202 1 times, resulting in a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 138 away from 202, we end up with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 138

Going ahead to step 5:
When dividing 641 by 138, we get 4 with a remainder of 89.
Write down 4 as next digit of the result. 
Result so far: 214.0
Subtract 552 from 641 to get 89.
Take the next digit (2) from the dividend and append it to 89, then repeat: 892 / 138

Moving on to step 6:
If we divide 892 by 138, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 2146.0
Deduct 828 from 892 and we're left with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 138

Let's proceed to step 7:
When dividing 645 by 138, we get 4 with a remainder of 93.
Put 4 as the next digit of the answer. 
Result so far: 21464.0
If we take 552 away from 645, we end up with 93.
Append the next digit (8) from the dividend to 93 and continue with: 938 / 138

Let's proceed to step 8:
The number 138 fits into 938 6 times, leaving a remainder of 110.
The next digit of our result is 6. 
Result so far: 214646.0
If we take 828 away from 938, we end up 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.

On to step 9:
When dividing 1100 by 138, we get 7 with a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 214646.7
If we subtract 966 from 1100, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
138 can be fit into 1340 9 times, resulting in a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 214646.79
Subtracting 1242 from 1340 leaves us 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.

On to step 11:
When dividing 980 by 138, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 214646.797
Deduct 966 from 980 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
If we divide 140 by 138, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 214646.7971
Subtract 138 from 140 to 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.

Going ahead to step 13:
20 divided by 138 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 214646.7971
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
If we divide 200 by 138, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 214646.797101
Deduct 138 from 200 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 15:
138 can be fit into 620 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 214646.7971014
Subtract 552 from 620 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
If we divide 680 by 138, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 214646.79710144
Deduct 552 from 680 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Our division results in 214646.79710144 with a remaining 1.28e-07.
