We're dividing 37971889 by 100 
We want to divide 37971889 by 100.

Step 1:
If we divide 3 by 100, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 100

Moving on to step 2:
When dividing 37 by 100, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 100

Advancing to step 3:
When dividing 379 by 100, we get 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 300 from 379, we get 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 100

Let's proceed to step 4:
When dividing 797 by 100, we get 7 with a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 97 after subtracting 700 from 797.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 100

Moving on to step 5:
100 goes into 971 9 times with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 379.0
The remainder is 71 after subtracting 900 from 971.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 100

Step 6:
100 can be fit into 718 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 3797.0
The remainder is 18 after subtracting 700 from 718.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 100

Moving on to step 7:
When dividing 188 by 100, we get 1 with a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 37971.0
Subtract 100 from 188 to get 88.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 100

Moving on to step 8:
889 divided by 100 is 8 with a remainder of 89.
The number 8 becomes the next digit in our result. 
Result so far: 379718.0
Subtracting 800 from 889 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
When dividing 890 by 100, we get 8 with a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 379718.8
Subtracting 800 from 890 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
100 can be fit into 900 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 379718.89
Deduct 900 from 900 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 100, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 379718.89
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 100 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 379718.89
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 379718.89 with a remainder of 0.0.
