55915067 ÷ 438 
We want to figure out the number of times 55915067 can be divided by 438.

Step 1:
438 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 438

Step 2:
When dividing 55 by 438, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 438

Going ahead to step 3:
If we divide 559 by 438, we get 1 and a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 438 from 559 and we're left with 121.
Include the next digit (1) from the dividend after 121, then repeat: 1211 / 438

Going ahead to step 4:
When dividing 1211 by 438, we get 2 with a remainder of 335.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 876 from 1211 leaves us with 335.
Fetch the next digit (5) from the dividend, attach it to 335 and continue: 3355 / 438

Going ahead to step 5:
438 goes into 3355 7 times with a remainder of 289.
The next digit of our result is 7. 
Result so far: 127.0
Subtract 3066 from 3355 to get 289.
Bring next digit (0) of the dividend behind the 289 and repeat the process: 2890 / 438

Advancing to step 6:
438 can be fit into 2890 6 times, resulting in a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
If we take 2628 away from 2890, we end up with 262.
Take the next digit (6) from the dividend and append it to 262, then repeat: 2626 / 438

On to step 7:
438 goes into 2626 5 times with a remainder of 436.
The next digit of our result is 5. 
Result so far: 12765.0
Subtract 2190 from 2626 to get 436.
Fetch the next digit (7) from the dividend, attach it to 436 and continue: 4367 / 438

Let's proceed to step 8:
438 can be fit into 4367 9 times, resulting in a remainder of 425.
Put 9 as the next digit of the answer. 
Result so far: 127659.0
If we take 3942 away from 4367, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 9:
If we divide 4250 by 438, we get 9 and a remainder of 308.
The next digit of our result is 9. 
Result so far: 127659.9
The remainder is 308 after subtracting 3942 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 10:
438 goes into 3080 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 127659.97
Deduct 3066 from 3080 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
438 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 127659.97
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
If we divide 1400 by 438, we get 3 and a remainder of 86.
The next digit of our result is 3. 
Result so far: 127659.9703
The remainder is 86 after subtracting 1314 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 13:
438 goes into 860 1 times with a remainder of 422.
Write down 1 as next digit of the result. 
Result so far: 127659.97031
Subtracting 438 from 860 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 14:
If we divide 4220 by 438, we get 9 and a remainder of 278.
Write down 9 as next digit of the result. 
Result so far: 127659.970319
Subtract 3942 from 4220 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 15:
438 can be fit into 2780 6 times, resulting in a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 127659.9703196
The remainder is 152 after subtracting 2628 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 16:
If we divide 1520 by 438, we get 3 and a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 127659.97031963
Subtract 1314 from 1520 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

After the division, we end up with 127659.97031963 and a remainder of 2.06e-07.
