Let's divide 13863644 by 890
We want to figure out the number of times 13863644 can be divided by 890.

Advancing to step 1:
890 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 890

Step 2:
The number 890 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 890

Moving on to step 3:
138 divided by 890 is 0 with a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Grab the next digit (6) from the dividend, add it to 138, then carry on: 1386 / 890

Advancing to step 4:
1386 divided by 890 is 1 with a remainder of 496.
The next digit of our result is 1. 
Result so far: 1.0
If we take 890 away from 1386, we end up with 496.
Grab the next digit (3) from the dividend, add it to 496, then carry on: 4963 / 890

On to step 5:
If we divide 4963 by 890, we get 5 and a remainder of 513.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 4450 from 4963 and we're left with 513.
Append the next digit (6) from the dividend to 513 and continue with: 5136 / 890

Moving on to step 6:
890 goes into 5136 5 times with a remainder of 686.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Deduct 4450 from 5136 and we're left with 686.
Include the next digit (4) from the dividend after 686, then repeat: 6864 / 890

Step 7:
890 goes into 6864 7 times with a remainder of 634.
Put 7 as the next digit of the answer. 
Result so far: 1557.0
Deduct 6230 from 6864 and we're left with 634.
Include the next digit (4) from the dividend after 634, then repeat: 6344 / 890

On to step 8:
6344 divided by 890 is 7 with a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 15577.0
Deduct 6230 from 6344 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
When dividing 1140 by 890, we get 1 with a remainder of 250.
The next digit of our result is 1. 
Result so far: 15577.1
Subtracting 890 from 1140 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
2500 divided by 890 is 2 with a remainder of 720.
The number 2 becomes the next digit in our result. 
Result so far: 15577.12
Subtracting 1780 from 2500 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 11:
890 goes into 7200 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 15577.128
If we subtract 7120 from 7200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
800 divided by 890 is 0 with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 15577.128
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 13:
8000 divided by 890 is 8 with a remainder of 880.
Record the quotient 8 as the next digit in the result. 
Result so far: 15577.12808
Subtracting 7120 from 8000 leaves us with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Let's proceed to step 14:
When dividing 8800 by 890, we get 9 with a remainder of 790.
The next digit of our result is 9. 
Result so far: 15577.128089
Deduct 8010 from 8800 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 15:
If we divide 7900 by 890, we get 8 and a remainder of 780.
Record the quotient 8 as the next digit in the result. 
Result so far: 15577.1280898
Subtract 7120 from 7900 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 16:
When dividing 7800 by 890, we get 8 with a remainder of 680.
Use 8 as the next digit of our solution. 
Result so far: 15577.12808988
Subtracting 7120 from 7800 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Our division results in 15577.12808988 with a remaining 6.8e-07.
