We're dividing 55060503 by 428 
We want to figure out the number of times 55060503 can be divided by 428.

On to step 1:
428 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 428

Let's proceed to step 2:
If we divide 55 by 428, we get 0 and a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 428

Let's proceed to step 3:
428 goes into 550 1 times with a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 428 from 550 to get 122.
Include the next digit (6) from the dividend after 122, then repeat: 1226 / 428

On to step 4:
428 can be fit into 1226 2 times, resulting in a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 856 from 1226 and we're left with 370.
Include the next digit (0) from the dividend after 370, then repeat: 3700 / 428

Step 5:
The number 428 fits into 3700 8 times, leaving a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we subtract 3424 from 3700, we get 276.
Append the next digit (5) from the dividend to 276 and continue with: 2765 / 428

Moving on to step 6:
428 can be fit into 2765 6 times, resulting in a remainder of 197.
The number 6 becomes the next digit in our result. 
Result so far: 1286.0
The remainder is 197 after subtracting 2568 from 2765.
Bring next digit (0) of the dividend behind the 197 and repeat the process: 1970 / 428

Going ahead to step 7:
428 goes into 1970 4 times with a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 12864.0
Subtracting 1712 from 1970 leaves us with 258.
Append the next digit (3) from the dividend to 258 and continue with: 2583 / 428

Going ahead to step 8:
When dividing 2583 by 428, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 128646.0
If we take 2568 away from 2583, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 428, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 128646.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
When dividing 1500 by 428, we get 3 with a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 128646.03
The remainder is 216 after subtracting 1284 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
When dividing 2160 by 428, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 128646.035
If we take 2140 away from 2160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 428, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 128646.035
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
The number 428 fits into 2000 4 times, leaving a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 128646.03504
If we take 1712 away from 2000, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
If we divide 2880 by 428, we get 6 and a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 128646.035046
If we take 2568 away from 2880, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 15:
When dividing 3120 by 428, we get 7 with a remainder of 124.
The number 7 becomes the next digit in our result. 
Result so far: 128646.0350467
Subtracting 2996 from 3120 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 16:
If we divide 1240 by 428, we get 2 and a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 128646.03504672
Subtracting 856 from 1240 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 128646.03504672, with a leftover of 3.84e-07.
