55488679 ÷ 438 
We want to figure out the number of times 55488679 can be divided by 438.

Moving on to step 1:
The number 438 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 438

Going ahead to step 2:
438 can be fit into 55 0 times, resulting in a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 438

Advancing to step 3:
If we divide 554 by 438, we get 1 and a remainder of 116.
The next digit of our result is 1. 
Result so far: 1.0
If we take 438 away from 554, we end up with 116.
Grab the next digit (8) from the dividend, add it to 116, then carry on: 1168 / 438

Moving on to step 4:
1168 divided by 438 is 2 with a remainder of 292.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 876 from 1168 leaves us with 292.
Take the next digit (8) from the dividend and append it to 292, then repeat: 2928 / 438

Let's proceed to step 5:
438 goes into 2928 6 times with a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 2628 away from 2928, we end up with 300.
Bring next digit (6) of the dividend behind the 300 and repeat the process: 3006 / 438

On to step 6:
The number 438 fits into 3006 6 times, leaving a remainder of 378.
Write down 6 as next digit of the result. 
Result so far: 1266.0
If we subtract 2628 from 3006, we get 378.
Include the next digit (7) from the dividend after 378, then repeat: 3787 / 438

On to step 7:
438 goes into 3787 8 times with a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 12668.0
If we take 3504 away from 3787, we end up with 283.
Append the next digit (9) from the dividend to 283 and continue with: 2839 / 438

Moving on to step 8:
438 goes into 2839 6 times with a remainder of 211.
Put 6 as the next digit of the answer. 
Result so far: 126686.0
Subtract 2628 from 2839 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
2110 divided by 438 is 4 with a remainder of 358.
Record the quotient 4 as the next digit in the result. 
Result so far: 126686.4
If we subtract 1752 from 2110, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 10:
438 can be fit into 3580 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 126686.48
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.

On to step 11:
438 goes into 760 1 times with a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 126686.481
If we subtract 438 from 760, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 12:
438 goes into 3220 7 times with a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 126686.4817
The remainder is 154 after subtracting 3066 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 13:
1540 divided by 438 is 3 with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 126686.48173
Subtracting 1314 from 1540 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 14:
If we divide 2260 by 438, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 126686.481735
Subtracting 2190 from 2260 leaves us 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.

Advancing to step 15:
The number 438 fits into 700 1 times, leaving a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 126686.4817351
Subtracting 438 from 700 leaves us 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.

On to step 16:
438 goes into 2620 5 times with a remainder of 430.
The next digit of our result is 5. 
Result so far: 126686.48173515
The remainder is 430 after subtracting 2190 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final result is 126686.48173515 with a remainder of 4.3e-07.
