We look at the division of 55109387 by 849 
We want to divide 55109387 by 849.

Step 1:
849 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
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 / 849

Advancing to step 2:
849 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 849

Advancing to step 3:
The number 849 fits into 551 0 times, leaving a remainder of 551.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 551, we end up with 551.
Append the next digit (0) from the dividend to 551 and continue with: 5510 / 849

Going ahead to step 4:
If we divide 5510 by 849, we get 6 and a remainder of 416.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5094 from 5510 and we're left with 416.
Append the next digit (9) from the dividend to 416 and continue with: 4169 / 849

On to step 5:
If we divide 4169 by 849, we get 4 and a remainder of 773.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Deduct 3396 from 4169 and we're left with 773.
Grab the next digit (3) from the dividend, add it to 773, then carry on: 7733 / 849

Advancing to step 6:
849 goes into 7733 9 times with a remainder of 92.
Write down 9 as next digit of the result. 
Result so far: 649.0
Subtract 7641 from 7733 to get 92.
Fetch the next digit (8) from the dividend, attach it to 92 and continue: 928 / 849

Advancing to step 7:
849 can be fit into 928 1 times, resulting in a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 6491.0
If we subtract 849 from 928, we get 79.
Grab the next digit (7) from the dividend, add it to 79, then carry on: 797 / 849

Advancing to step 8:
849 goes into 797 0 times with a remainder of 797.
Use 0 as the next digit of our solution. 
Result so far: 64910.0
Subtract 0 from 797 to get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Advancing to step 9:
If we divide 7970 by 849, we get 9 and a remainder of 329.
Put 9 as the next digit of the answer. 
Result so far: 64910.9
The remainder is 329 after subtracting 7641 from 7970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 10:
The number 849 fits into 3290 3 times, leaving a remainder of 743.
Write down 3 as next digit of the result. 
Result so far: 64910.93
Subtract 2547 from 3290 to get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

On to step 11:
7430 divided by 849 is 8 with a remainder of 638.
The number 8 becomes the next digit in our result. 
Result so far: 64910.938
Subtract 6792 from 7430 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Let's proceed to step 12:
849 can be fit into 6380 7 times, resulting in a remainder of 437.
The next digit of our result is 7. 
Result so far: 64910.9387
The remainder is 437 after subtracting 5943 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 13:
If we divide 4370 by 849, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 64910.93875
Subtract 4245 from 4370 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 14:
The number 849 fits into 1250 1 times, leaving a remainder of 401.
The next digit of our result is 1. 
Result so far: 64910.938751
If we take 849 away from 1250, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 15:
If we divide 4010 by 849, we get 4 and a remainder of 614.
The number 4 becomes the next digit in our result. 
Result so far: 64910.9387514
If we subtract 3396 from 4010, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 16:
849 can be fit into 6140 7 times, resulting in a remainder of 197.
Write down 7 as next digit of the result. 
Result so far: 64910.93875147
Subtract 5943 from 6140 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final result is 64910.93875147 with a remainder of 1.97e-07.
