We're dividing 13890288 by 37 
We want to figure out the number of times 13890288 can be divided by 37.

On to step 1:
1 divided by 37 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 37

Step 2:
37 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 37

Advancing to step 3:
The number 37 fits into 138 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 111 from 138, we get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 37

Let's proceed to step 4:
37 goes into 279 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 20 after subtracting 259 from 279.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 37

Step 5:
200 divided by 37 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 375.0
Deduct 185 from 200 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 37

Advancing to step 6:
37 can be fit into 152 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3754.0
If we take 148 away from 152, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 37

Step 7:
37 can be fit into 48 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 37541.0
Deduct 37 from 48 and we're left with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 37

Step 8:
When dividing 118 by 37, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 375413.0
If we subtract 111 from 118, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
37 can be fit into 70 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 375413.1
Deduct 37 from 70 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
37 goes into 330 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 375413.18
If we take 296 away from 330, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
37 goes into 340 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 375413.189
Subtract 333 from 340 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
37 goes into 70 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 375413.1891
If we subtract 37 from 70, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
When dividing 330 by 37, we get 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 375413.18918
Deduct 296 from 330 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
37 can be fit into 340 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 375413.189189
Deduct 333 from 340 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 15:
If we divide 70 by 37, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 375413.1891891
Subtract 37 from 70 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 16:
If we divide 330 by 37, we get 8 and a remainder of 34.
The next digit of our result is 8. 
Result so far: 375413.18918918
Subtract 296 from 330 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 375413.18918918, with a leftover of 3.4e-08.
