We look at the division of 11639400 by 801 
We're looking to find how many times 801 goes into 11639400.

Step 1:
801 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 801

Step 2:
The number 801 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 801

Advancing to step 3:
The number 801 fits into 116 0 times, leaving a remainder of 116.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 116 after subtracting 0 from 116.
Bring next digit (3) of the dividend behind the 116 and repeat the process: 1163 / 801

Moving on to step 4:
801 goes into 1163 1 times with a remainder of 362.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 801 away from 1163, we end up with 362.
Append the next digit (9) from the dividend to 362 and continue with: 3629 / 801

On to step 5:
If we divide 3629 by 801, we get 4 and a remainder of 425.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 3204 from 3629, we get 425.
Grab the next digit (4) from the dividend, add it to 425, then carry on: 4254 / 801

Step 6:
801 goes into 4254 5 times with a remainder of 249.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we subtract 4005 from 4254, we get 249.
Fetch the next digit (0) from the dividend, attach it to 249 and continue: 2490 / 801

Step 7:
When dividing 2490 by 801, we get 3 with a remainder of 87.
The next digit of our result is 3. 
Result so far: 1453.0
If we subtract 2403 from 2490, we get 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 801

Step 8:
If we divide 870 by 801, we get 1 and a remainder of 69.
The next digit of our result is 1. 
Result so far: 14531.0
If we subtract 801 from 870, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
If we divide 690 by 801, we get 0 and a remainder of 690.
Use 0 as the next digit of our solution. 
Result so far: 14531.0
Deduct 0 from 690 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 10:
The number 801 fits into 6900 8 times, leaving a remainder of 492.
The next digit of our result is 8. 
Result so far: 14531.08
If we subtract 6408 from 6900, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 11:
801 goes into 4920 6 times with a remainder of 114.
The number 6 becomes the next digit in our result. 
Result so far: 14531.086
If we take 4806 away from 4920, we end up 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.

Moving on to step 12:
1140 divided by 801 is 1 with a remainder of 339.
The next digit of our result is 1. 
Result so far: 14531.0861
If we take 801 away from 1140, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 13:
If we divide 3390 by 801, we get 4 and a remainder of 186.
Record the quotient 4 as the next digit in the result. 
Result so far: 14531.08614
If we subtract 3204 from 3390, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 14:
The number 801 fits into 1860 2 times, leaving a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 14531.086142
The remainder is 258 after subtracting 1602 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 15:
When dividing 2580 by 801, we get 3 with a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 14531.0861423
Subtract 2403 from 2580 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 16:
1770 divided by 801 is 2 with a remainder of 168.
The next digit of our result is 2. 
Result so far: 14531.08614232
Subtracting 1602 from 1770 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 14531.08614232 and a remainder of 1.68e-07.
