78482169 ÷ 551 
We want to divide 78482169 by 551.

Moving on to step 1:
If we divide 7 by 551, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 551

Let's proceed to step 2:
If we divide 78 by 551, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 551

Going ahead to step 3:
551 goes into 784 1 times with a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 233 after subtracting 551 from 784.
Append the next digit (8) from the dividend to 233 and continue with: 2338 / 551

Step 4:
551 can be fit into 2338 4 times, resulting in a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2204 from 2338 and we're left with 134.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 551

Advancing to step 5:
When dividing 1342 by 551, we get 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 142.0
Subtracting 1102 from 1342 leaves us with 240.
Append the next digit (1) from the dividend to 240 and continue with: 2401 / 551

Moving on to step 6:
551 can be fit into 2401 4 times, resulting in a remainder of 197.
The number 4 becomes the next digit in our result. 
Result so far: 1424.0
If we take 2204 away from 2401, we end up with 197.
Include the next digit (6) from the dividend after 197, then repeat: 1976 / 551

Advancing to step 7:
When dividing 1976 by 551, we get 3 with a remainder of 323.
Use 3 as the next digit of our solution. 
Result so far: 14243.0
If we take 1653 away from 1976, we end up with 323.
Bring next digit (9) of the dividend behind the 323 and repeat the process: 3239 / 551

Going ahead to step 8:
The number 551 fits into 3239 5 times, leaving a remainder of 484.
Put 5 as the next digit of the answer. 
Result so far: 142435.0
If we subtract 2755 from 3239, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 9:
4840 divided by 551 is 8 with a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 142435.8
If we take 4408 away from 4840, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 10:
If we divide 4320 by 551, we get 7 and a remainder of 463.
Record the quotient 7 as the next digit in the result. 
Result so far: 142435.87
The remainder is 463 after subtracting 3857 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 11:
The number 551 fits into 4630 8 times, leaving a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 142435.878
Deduct 4408 from 4630 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 12:
551 goes into 2220 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 142435.8784
Subtract 2204 from 2220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
551 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 142435.8784
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
If we divide 1600 by 551, we get 2 and a remainder of 498.
Write down 2 as next digit of the result. 
Result so far: 142435.878402
If we take 1102 away from 1600, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 15:
4980 divided by 551 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 142435.8784029
If we take 4959 away from 4980, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 16:
If we divide 210 by 551, we get 0 and a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 142435.8784029
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 142435.8784029 with a remaining 2.1e-07.
