75210037 divided by 20 
We want to divide 75210037 by 20.

On to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 20

Step 2:
20 can be fit into 75 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 75, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 20

Going ahead to step 3:
When dividing 152 by 20, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 140 from 152 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 20

On to step 4:
121 divided by 20 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 376.0
If we subtract 120 from 121, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 20

Step 5:
10 divided by 20 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 3760.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 20

Let's proceed to step 6:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 37605.0
Deduct 100 from 100 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 20

Moving on to step 7:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 376050.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

Let's proceed to step 8:
When dividing 37 by 20, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 3760501.0
If we subtract 20 from 37, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 3760501.8
Deduct 160 from 170 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3760501.85
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3760501.85
If we subtract 0 from 0, we 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.

Going ahead to step 12:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3760501.85
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.

The final outcome is 3760501.85, with a leftover of 0.0.
