74354788 ÷ 20 
Let's see how many times 20 fits into 74354788.

Moving on to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 20

Step 2:
20 can be fit into 74 3 times, resulting in a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 60 from 74 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 20

Going ahead to step 3:
If we divide 143 by 20, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 140 from 143, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Going ahead to step 4:
When dividing 35 by 20, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 371.0
Subtracting 20 from 35 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 20

Going ahead to step 5:
20 can be fit into 154 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 3717.0
If we subtract 140 from 154, we get 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 20

Let's proceed to step 6:
147 divided by 20 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 37177.0
The remainder is 7 after subtracting 140 from 147.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 20

Moving on to step 7:
20 can be fit into 78 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 371773.0
If we take 60 away from 78, we end up with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 20

On to step 8:
When dividing 188 by 20, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 3717739.0
Subtract 180 from 188 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 20, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3717739.4
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3717739.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3717739.4
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.

The final outcome is 3717739.4, with a leftover of 0.0.
