98519960 ÷ 138 
We want to figure out the number of times 98519960 can be divided by 138.

Let's proceed to step 1:
When dividing 9 by 138, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 138

Moving on to step 2:
If we divide 98 by 138, we get 0 and a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (5) from the dividend after 98, then repeat: 985 / 138

Moving on to step 3:
985 divided by 138 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 19 after subtracting 966 from 985.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 138

Advancing to step 4:
138 can be fit into 191 1 times, resulting in a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we take 138 away from 191, we end up with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 138

Let's proceed to step 5:
When dividing 539 by 138, we get 3 with a remainder of 125.
Use 3 as the next digit of our solution. 
Result so far: 713.0
Subtract 414 from 539 to get 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 138

Step 6:
If we divide 1259 by 138, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 7139.0
If we take 1242 away from 1259, we end up with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 138

Advancing to step 7:
138 goes into 176 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 71391.0
Subtract 138 from 176 to get 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 138

On to step 8:
138 goes into 380 2 times with a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 713912.0
Subtract 276 from 380 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 9:
138 goes into 1040 7 times with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 713912.7
Deduct 966 from 1040 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
When dividing 740 by 138, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 713912.75
Subtract 690 from 740 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
If we divide 500 by 138, we get 3 and a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 713912.753
Subtracting 414 from 500 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
When dividing 860 by 138, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 713912.7536
Subtract 828 from 860 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
320 divided by 138 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 713912.75362
Subtract 276 from 320 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
138 goes into 440 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 713912.753623
If we subtract 414 from 440, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
The number 138 fits into 260 1 times, leaving a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 713912.7536231
If we take 138 away from 260, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 16:
When dividing 1220 by 138, we get 8 with a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 713912.75362318
The remainder is 116 after subtracting 1104 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final result is 713912.75362318 with a remainder of 1.16e-07.
