We look at the division of 74192378 by 748 
We want to divide 74192378 by 748.

Let's proceed to step 1:
When dividing 7 by 748, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 748

On to step 2:
748 goes into 74 0 times with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 748

On to step 3:
741 divided by 748 is 0 with a remainder of 741.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 741 and we're left with 741.
Grab the next digit (9) from the dividend, add it to 741, then carry on: 7419 / 748

On to step 4:
When dividing 7419 by 748, we get 9 with a remainder of 687.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 6732 from 7419 and we're left with 687.
Bring next digit (2) of the dividend behind the 687 and repeat the process: 6872 / 748

Let's proceed to step 5:
If we divide 6872 by 748, we get 9 and a remainder of 140.
The next digit of our result is 9. 
Result so far: 99.0
If we take 6732 away from 6872, we end up with 140.
Append the next digit (3) from the dividend to 140 and continue with: 1403 / 748

Advancing to step 6:
1403 divided by 748 is 1 with a remainder of 655.
Put 1 as the next digit of the answer. 
Result so far: 991.0
Subtract 748 from 1403 to get 655.
Grab the next digit (7) from the dividend, add it to 655, then carry on: 6557 / 748

Moving on to step 7:
When dividing 6557 by 748, we get 8 with a remainder of 573.
Record the quotient 8 as the next digit in the result. 
Result so far: 9918.0
If we take 5984 away from 6557, we end up with 573.
Append the next digit (8) from the dividend to 573 and continue with: 5738 / 748

Step 8:
When dividing 5738 by 748, we get 7 with a remainder of 502.
Record the quotient 7 as the next digit in the result. 
Result so far: 99187.0
Deduct 5236 from 5738 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 9:
If we divide 5020 by 748, we get 6 and a remainder of 532.
The next digit of our result is 6. 
Result so far: 99187.6
If we take 4488 away from 5020, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 10:
If we divide 5320 by 748, we get 7 and a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 99187.67
Deduct 5236 from 5320 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
748 can be fit into 840 1 times, resulting in a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 99187.671
The remainder is 92 after subtracting 748 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
920 divided by 748 is 1 with a remainder of 172.
The number 1 becomes the next digit in our result. 
Result so far: 99187.6711
The remainder is 172 after subtracting 748 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 99187.6711 and a remainder of 0.00172.
