70077031 ÷ 438 
We want to figure out the number of times 70077031 can be divided by 438.

Advancing to step 1:
When dividing 7 by 438, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 438

Advancing to step 2:
The number 438 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 438

Let's proceed to step 3:
438 can be fit into 700 1 times, resulting in a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 438 away from 700, we end up with 262.
Append the next digit (7) from the dividend to 262 and continue with: 2627 / 438

Step 4:
If we divide 2627 by 438, we get 5 and a remainder of 437.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2190 away from 2627, we end up with 437.
Bring next digit (7) of the dividend behind the 437 and repeat the process: 4377 / 438

On to step 5:
The number 438 fits into 4377 9 times, leaving a remainder of 435.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 3942 from 4377 to get 435.
Fetch the next digit (0) from the dividend, attach it to 435 and continue: 4350 / 438

Advancing to step 6:
438 can be fit into 4350 9 times, resulting in a remainder of 408.
Put 9 as the next digit of the answer. 
Result so far: 1599.0
Subtract 3942 from 4350 to get 408.
Grab the next digit (3) from the dividend, add it to 408, then carry on: 4083 / 438

Moving on to step 7:
The number 438 fits into 4083 9 times, leaving a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 15999.0
If we take 3942 away from 4083, we end up with 141.
Grab the next digit (1) from the dividend, add it to 141, then carry on: 1411 / 438

On to step 8:
When dividing 1411 by 438, we get 3 with a remainder of 97.
Record the quotient 3 as the next digit in the result. 
Result so far: 159993.0
If we subtract 1314 from 1411, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
970 divided by 438 is 2 with a remainder of 94.
The next digit of our result is 2. 
Result so far: 159993.2
Deduct 876 from 970 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
940 divided by 438 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 159993.22
If we subtract 876 from 940, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 159993.22, and the remainder is 0.064.
