138644 divided by 93 
We're looking to find how many times 93 goes into 138644.

Going ahead to step 1:
If we divide 1 by 93, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 93

On to step 2:
When dividing 13 by 93, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 93

Going ahead to step 3:
93 can be fit into 138 1 times, resulting in a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 93 from 138 leaves us with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 93

Advancing to step 4:
If we divide 456 by 93, we get 4 and a remainder of 84.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 372 from 456, we get 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 93

Step 5:
When dividing 844 by 93, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 149.0
Deduct 837 from 844 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 93

Moving on to step 6:
When dividing 74 by 93, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 1490.0
If we subtract 0 from 74, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
93 goes into 740 7 times with a remainder of 89.
Record the quotient 7 as the next digit in the result. 
Result so far: 1490.7
Subtract 651 from 740 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 8:
The number 93 fits into 890 9 times, leaving a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 1490.79
The remainder is 53 after subtracting 837 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
The number 93 fits into 530 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1490.795
Subtracting 465 from 530 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
When dividing 650 by 93, we get 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 1490.7956
If we subtract 558 from 650, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
93 goes into 920 9 times with a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 1490.79569
If we take 837 away from 920, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
When dividing 830 by 93, we get 8 with a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 1490.795698
If we take 744 away from 830, we end up 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.

On to step 13:
The number 93 fits into 860 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 1490.7956989
If we take 837 away from 860, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
230 divided by 93 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 1490.79569892
Deduct 186 from 230 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 1490.79569892 and a remainder of 4.4e-08.
