75037969 divided by 210 
We're looking to find how many times 210 goes into 75037969.

Moving on to step 1:
When dividing 7 by 210, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 210

Let's proceed to step 2:
75 divided by 210 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 210

On to step 3:
When dividing 750 by 210, we get 3 with a remainder of 120.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 630 from 750 leaves us with 120.
Append the next digit (3) from the dividend to 120 and continue with: 1203 / 210

Advancing to step 4:
When dividing 1203 by 210, we get 5 with a remainder of 153.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 153 after subtracting 1050 from 1203.
Fetch the next digit (7) from the dividend, attach it to 153 and continue: 1537 / 210

Moving on to step 5:
If we divide 1537 by 210, we get 7 and a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
If we subtract 1470 from 1537, we get 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 210

Step 6:
210 goes into 679 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 3573.0
The remainder is 49 after subtracting 630 from 679.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 210

Moving on to step 7:
210 goes into 496 2 times with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 35732.0
If we subtract 420 from 496, we get 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 210

Advancing to step 8:
If we divide 769 by 210, we get 3 and a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 357323.0
Subtracting 630 from 769 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 9:
If we divide 1390 by 210, we get 6 and a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 357323.6
If we subtract 1260 from 1390, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
210 can be fit into 1300 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 357323.66
Subtracting 1260 from 1300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 357323.66, with a leftover of 0.04.
