We look at the division of 99506966 by 138 
We want to divide 99506966 by 138.

Let's proceed to step 1:
The number 138 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 138

Let's proceed to step 2:
138 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 138

Advancing to step 3:
When dividing 995 by 138, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 966 from 995 to get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 138

Let's proceed to step 4:
When dividing 290 by 138, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we subtract 276 from 290, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 138

Going ahead to step 5:
If we divide 146 by 138, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 721.0
The remainder is 8 after subtracting 138 from 146.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 138

Moving on to step 6:
When dividing 89 by 138, we get 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 7210.0
Deduct 0 from 89 and we're left with 89.
Include the next digit (6) from the dividend after 89, then repeat: 896 / 138

Advancing to step 7:
If we divide 896 by 138, we get 6 and a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 72106.0
If we take 828 away from 896, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 138

Let's proceed to step 8:
If we divide 686 by 138, we get 4 and a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 721064.0
If we subtract 552 from 686, 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.

Step 9:
138 goes into 1340 9 times with a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 721064.9
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.

On to step 10:
138 can be fit into 980 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 721064.97
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 11:
140 divided by 138 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 721064.971
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
138 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 721064.971
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.

Let's proceed to step 13:
138 can be fit into 200 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 721064.97101
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.

Let's proceed to step 14:
If we divide 620 by 138, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 721064.971014
Deduct 552 from 620 and we're left 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.

Let's proceed to step 15:
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: 721064.9710144
Subtract 552 from 680 to get 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 721064.9710144 with a remaining 1.28e-06.
