64025406 ÷ 551 
We want to figure out the number of times 64025406 can be divided by 551.

Going ahead to step 1:
6 divided by 551 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 551

Advancing to step 2:
When dividing 64 by 551, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 551

Moving on to step 3:
640 divided by 551 is 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 551 from 640 and we're left with 89.
Append the next digit (2) from the dividend to 89 and continue with: 892 / 551

Advancing to step 4:
551 can be fit into 892 1 times, resulting in a remainder of 341.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 341 after subtracting 551 from 892.
Take the next digit (5) from the dividend and append it to 341, then repeat: 3415 / 551

Let's proceed to step 5:
3415 divided by 551 is 6 with a remainder of 109.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we subtract 3306 from 3415, we get 109.
Take the next digit (4) from the dividend and append it to 109, then repeat: 1094 / 551

Going ahead to step 6:
If we divide 1094 by 551, we get 1 and a remainder of 543.
Write down 1 as next digit of the result. 
Result so far: 1161.0
If we take 551 away from 1094, we end up with 543.
Take the next digit (0) from the dividend and append it to 543, then repeat: 5430 / 551

Let's proceed to step 7:
551 goes into 5430 9 times with a remainder of 471.
Record the quotient 9 as the next digit in the result. 
Result so far: 11619.0
If we take 4959 away from 5430, we end up with 471.
Fetch the next digit (6) from the dividend, attach it to 471 and continue: 4716 / 551

Step 8:
If we divide 4716 by 551, we get 8 and a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 116198.0
Deduct 4408 from 4716 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 9:
The number 551 fits into 3080 5 times, leaving a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 116198.5
If we subtract 2755 from 3080, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 10:
When dividing 3250 by 551, we get 5 with a remainder of 495.
Put 5 as the next digit of the answer. 
Result so far: 116198.55
Deduct 2755 from 3250 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The final outcome is 116198.55, with a leftover of 0.495.
