74557717 ÷ 438 
Our goal is to divide 74557717 by 438.

On to step 1:
438 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 438

Moving on to step 2:
438 can be fit into 74 0 times, resulting in a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 438

On to step 3:
If we divide 745 by 438, we get 1 and a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 307 after subtracting 438 from 745.
Grab the next digit (5) from the dividend, add it to 307, then carry on: 3075 / 438

Let's proceed to step 4:
438 can be fit into 3075 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 9 after subtracting 3066 from 3075.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 438

Advancing to step 5:
438 can be fit into 97 0 times, resulting in a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 97 leaves us with 97.
Fetch the next digit (7) from the dividend, attach it to 97 and continue: 977 / 438

Step 6:
When dividing 977 by 438, we get 2 with a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 1702.0
Subtract 876 from 977 to get 101.
Fetch the next digit (1) from the dividend, attach it to 101 and continue: 1011 / 438

Moving on to step 7:
1011 divided by 438 is 2 with a remainder of 135.
Record the quotient 2 as the next digit in the result. 
Result so far: 17022.0
Deduct 876 from 1011 and we're left with 135.
Append the next digit (7) from the dividend to 135 and continue with: 1357 / 438

On to step 8:
438 can be fit into 1357 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 170223.0
Deduct 1314 from 1357 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
If we divide 430 by 438, we get 0 and a remainder of 430.
The next digit of our result is 0. 
Result so far: 170223.0
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
The number 438 fits into 4300 9 times, leaving a remainder of 358.
The next digit of our result is 9. 
Result so far: 170223.09
If we take 3942 away from 4300, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 11:
The number 438 fits into 3580 8 times, leaving a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 170223.098
If we subtract 3504 from 3580, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
438 goes into 760 1 times with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 170223.0981
Subtracting 438 from 760 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 13:
If we divide 3220 by 438, we get 7 and a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 170223.09817
If we subtract 3066 from 3220, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 14:
438 can be fit into 1540 3 times, resulting in a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 170223.098173
Subtract 1314 from 1540 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 15:
2260 divided by 438 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 170223.0981735
Deduct 2190 from 2260 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
The number 438 fits into 700 1 times, leaving a remainder of 262.
Write down 1 as next digit of the result. 
Result so far: 170223.09817351
Deduct 438 from 700 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Our division results in 170223.09817351 with a remaining 2.62e-07.
