57983438 ÷ 849 
We want to divide 57983438 by 849.

Step 1:
849 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 849

Going ahead to step 2:
The number 849 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 849

Let's proceed to step 3:
If we divide 579 by 849, we get 0 and a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 579, we end up with 579.
Bring next digit (8) of the dividend behind the 579 and repeat the process: 5798 / 849

Going ahead to step 4:
If we divide 5798 by 849, we get 6 and a remainder of 704.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 704 after subtracting 5094 from 5798.
Bring next digit (3) of the dividend behind the 704 and repeat the process: 7043 / 849

Step 5:
849 can be fit into 7043 8 times, resulting in a remainder of 251.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 251 after subtracting 6792 from 7043.
Take the next digit (4) from the dividend and append it to 251, then repeat: 2514 / 849

Moving on to step 6:
If we divide 2514 by 849, we get 2 and a remainder of 816.
Use 2 as the next digit of our solution. 
Result so far: 682.0
If we subtract 1698 from 2514, we get 816.
Grab the next digit (3) from the dividend, add it to 816, then carry on: 8163 / 849

On to step 7:
849 goes into 8163 9 times with a remainder of 522.
Record the quotient 9 as the next digit in the result. 
Result so far: 6829.0
If we subtract 7641 from 8163, we get 522.
Take the next digit (8) from the dividend and append it to 522, then repeat: 5228 / 849

Going ahead to step 8:
When dividing 5228 by 849, we get 6 with a remainder of 134.
The next digit of our result is 6. 
Result so far: 68296.0
Deduct 5094 from 5228 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
If we divide 1340 by 849, we get 1 and a remainder of 491.
The next digit of our result is 1. 
Result so far: 68296.1
If we subtract 849 from 1340, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 10:
849 goes into 4910 5 times with a remainder of 665.
Record the quotient 5 as the next digit in the result. 
Result so far: 68296.15
The remainder is 665 after subtracting 4245 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 11:
If we divide 6650 by 849, we get 7 and a remainder of 707.
The next digit of our result is 7. 
Result so far: 68296.157
If we subtract 5943 from 6650, we get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Step 12:
If we divide 7070 by 849, we get 8 and a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 68296.1578
If we subtract 6792 from 7070, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 13:
2780 divided by 849 is 3 with a remainder of 233.
Put 3 as the next digit of the answer. 
Result so far: 68296.15783
If we subtract 2547 from 2780, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 14:
If we divide 2330 by 849, we get 2 and a remainder of 632.
Record the quotient 2 as the next digit in the result. 
Result so far: 68296.157832
Deduct 1698 from 2330 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 15:
6320 divided by 849 is 7 with a remainder of 377.
Use 7 as the next digit of our solution. 
Result so far: 68296.1578327
Subtracting 5943 from 6320 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Step 16:
849 goes into 3770 4 times with a remainder of 374.
Use 4 as the next digit of our solution. 
Result so far: 68296.15783274
Deduct 3396 from 3770 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The final outcome is 68296.15783274, with a leftover of 3.74e-07.
