55351887 ÷ 869 
We want to divide 55351887 by 869.

Let's proceed to step 1:
The number 869 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 869

Step 2:
869 goes into 55 0 times with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 869

Moving on to step 3:
553 divided by 869 is 0 with a remainder of 553.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 553, we end up with 553.
Fetch the next digit (5) from the dividend, attach it to 553 and continue: 5535 / 869

On to step 4:
5535 divided by 869 is 6 with a remainder of 321.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 5214 from 5535 and we're left with 321.
Take the next digit (1) from the dividend and append it to 321, then repeat: 3211 / 869

Moving on to step 5:
The number 869 fits into 3211 3 times, leaving a remainder of 604.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
The remainder is 604 after subtracting 2607 from 3211.
Fetch the next digit (8) from the dividend, attach it to 604 and continue: 6048 / 869

Advancing to step 6:
When dividing 6048 by 869, we get 6 with a remainder of 834.
Write down 6 as next digit of the result. 
Result so far: 636.0
If we subtract 5214 from 6048, we get 834.
Fetch the next digit (8) from the dividend, attach it to 834 and continue: 8348 / 869

On to step 7:
869 goes into 8348 9 times with a remainder of 527.
The number 9 becomes the next digit in our result. 
Result so far: 6369.0
Subtract 7821 from 8348 to get 527.
Fetch the next digit (7) from the dividend, attach it to 527 and continue: 5277 / 869

Step 8:
The number 869 fits into 5277 6 times, leaving a remainder of 63.
The next digit of our result is 6. 
Result so far: 63696.0
Subtract 5214 from 5277 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
If we divide 630 by 869, we get 0 and a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 63696.0
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 10:
869 goes into 6300 7 times with a remainder of 217.
Use 7 as the next digit of our solution. 
Result so far: 63696.07
Subtract 6083 from 6300 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 11:
869 can be fit into 2170 2 times, resulting in a remainder of 432.
Write down 2 as next digit of the result. 
Result so far: 63696.072
Subtract 1738 from 2170 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
869 can be fit into 4320 4 times, resulting in a remainder of 844.
Use 4 as the next digit of our solution. 
Result so far: 63696.0724
Deduct 3476 from 4320 and we're left with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Moving on to step 13:
869 goes into 8440 9 times with a remainder of 619.
Record the quotient 9 as the next digit in the result. 
Result so far: 63696.07249
If we subtract 7821 from 8440, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 14:
6190 divided by 869 is 7 with a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 63696.072497
Deduct 6083 from 6190 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 15:
869 can be fit into 1070 1 times, resulting in a remainder of 201.
The next digit of our result is 1. 
Result so far: 63696.0724971
If we subtract 869 from 1070, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 16:
If we divide 2010 by 869, we get 2 and a remainder of 272.
Use 2 as the next digit of our solution. 
Result so far: 63696.07249712
If we take 1738 away from 2010, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

In conclusion, the division gives 63696.07249712 with a balance of 2.72e-07.
