We look at the division of 75431890 by 189 
We're looking to find how many times 189 goes into 75431890.

Going ahead to step 1:
189 can be fit into 7 0 times, resulting in 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.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 189

On to step 2:
75 divided by 189 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 189

On to step 3:
The number 189 fits into 754 3 times, leaving a remainder of 187.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 567 from 754 to get 187.
Include the next digit (3) from the dividend after 187, then repeat: 1873 / 189

On to step 4:
189 goes into 1873 9 times with a remainder of 172.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 1701 from 1873 leaves us with 172.
Grab the next digit (1) from the dividend, add it to 172, then carry on: 1721 / 189

Let's proceed to step 5:
When dividing 1721 by 189, we get 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 399.0
If we subtract 1701 from 1721, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 189

Let's proceed to step 6:
189 can be fit into 208 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 3991.0
Subtracting 189 from 208 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 189

Advancing to step 7:
If we divide 199 by 189, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 39911.0
The remainder is 10 after subtracting 189 from 199.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 189

Let's proceed to step 8:
The number 189 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 399110.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 9:
189 can be fit into 1000 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 399110.5
Subtract 945 from 1000 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
189 can be fit into 550 2 times, resulting in a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 399110.52
Deduct 378 from 550 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
The number 189 fits into 1720 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 399110.529
Subtract 1701 from 1720 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
189 goes into 190 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 399110.5291
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
The number 189 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 399110.5291
Subtracting 0 from 10 leaves us 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 14:
When dividing 100 by 189, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 399110.5291
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 399110.5291, with a leftover of 1e-05.
