Let's divide 42109748 by 975
We want to figure out the number of times 42109748 can be divided by 975.

Moving on to step 1:
975 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 975

On to step 2:
975 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 975

Going ahead to step 3:
The number 975 fits into 421 0 times, leaving a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Fetch the next digit (0) from the dividend, attach it to 421 and continue: 4210 / 975

On to step 4:
The number 975 fits into 4210 4 times, leaving a remainder of 310.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 310 after subtracting 3900 from 4210.
Append the next digit (9) from the dividend to 310 and continue with: 3109 / 975

On to step 5:
When dividing 3109 by 975, we get 3 with a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 2925 from 3109 and we're left with 184.
Grab the next digit (7) from the dividend, add it to 184, then carry on: 1847 / 975

Going ahead to step 6:
If we divide 1847 by 975, we get 1 and a remainder of 872.
Use 1 as the next digit of our solution. 
Result so far: 431.0
Subtracting 975 from 1847 leaves us with 872.
Bring next digit (4) of the dividend behind the 872 and repeat the process: 8724 / 975

Advancing to step 7:
When dividing 8724 by 975, we get 8 with a remainder of 924.
Record the quotient 8 as the next digit in the result. 
Result so far: 4318.0
Subtract 7800 from 8724 to get 924.
Grab the next digit (8) from the dividend, add it to 924, then carry on: 9248 / 975

Moving on to step 8:
When dividing 9248 by 975, we get 9 with a remainder of 473.
Write down 9 as next digit of the result. 
Result so far: 43189.0
If we subtract 8775 from 9248, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 9:
If we divide 4730 by 975, we get 4 and a remainder of 830.
Put 4 as the next digit of the answer. 
Result so far: 43189.4
Subtract 3900 from 4730 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Advancing to step 10:
8300 divided by 975 is 8 with a remainder of 500.
Write down 8 as next digit of the result. 
Result so far: 43189.48
If we subtract 7800 from 8300, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
5000 divided by 975 is 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 43189.485
Deduct 4875 from 5000 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
975 goes into 1250 1 times with a remainder of 275.
Record the quotient 1 as the next digit in the result. 
Result so far: 43189.4851
If we subtract 975 from 1250, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 13:
975 goes into 2750 2 times with a remainder of 800.
The next digit of our result is 2. 
Result so far: 43189.48512
Deduct 1950 from 2750 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 14:
When dividing 8000 by 975, we get 8 with a remainder of 200.
The next digit of our result is 8. 
Result so far: 43189.485128
Subtract 7800 from 8000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
975 goes into 2000 2 times with a remainder of 50.
The next digit of our result is 2. 
Result so far: 43189.4851282
Subtracting 1950 from 2000 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
If we divide 500 by 975, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 43189.4851282
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 43189.4851282 and a remainder of 5e-07.
