66838335 ÷ 548 
We want to divide 66838335 by 548.

Let's proceed to step 1:
The number 548 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 548

Going ahead to step 2:
When dividing 66 by 548, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 548

Let's proceed to step 3:
668 divided by 548 is 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 120 after subtracting 548 from 668.
Include the next digit (3) from the dividend after 120, then repeat: 1203 / 548

Advancing to step 4:
548 goes into 1203 2 times with a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1096 from 1203 and we're left with 107.
Fetch the next digit (8) from the dividend, attach it to 107 and continue: 1078 / 548

On to step 5:
If we divide 1078 by 548, we get 1 and a remainder of 530.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtract 548 from 1078 to get 530.
Take the next digit (3) from the dividend and append it to 530, then repeat: 5303 / 548

Advancing to step 6:
548 can be fit into 5303 9 times, resulting in a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 1219.0
The remainder is 371 after subtracting 4932 from 5303.
Include the next digit (3) from the dividend after 371, then repeat: 3713 / 548

Advancing to step 7:
When dividing 3713 by 548, we get 6 with a remainder of 425.
Use 6 as the next digit of our solution. 
Result so far: 12196.0
Deduct 3288 from 3713 and we're left with 425.
Take the next digit (5) from the dividend and append it to 425, then repeat: 4255 / 548

Moving on to step 8:
If we divide 4255 by 548, we get 7 and a remainder of 419.
Write down 7 as next digit of the result. 
Result so far: 121967.0
Subtract 3836 from 4255 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 9:
548 can be fit into 4190 7 times, resulting in a remainder of 354.
Write down 7 as next digit of the result. 
Result so far: 121967.7
Subtract 3836 from 4190 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 10:
548 can be fit into 3540 6 times, resulting in a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 121967.76
Subtract 3288 from 3540 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
2520 divided by 548 is 4 with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 121967.764
If we take 2192 away from 2520, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
When dividing 3280 by 548, we get 5 with a remainder of 540.
The next digit of our result is 5. 
Result so far: 121967.7645
The remainder is 540 after subtracting 2740 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 13:
If we divide 5400 by 548, we get 9 and a remainder of 468.
Use 9 as the next digit of our solution. 
Result so far: 121967.76459
Deduct 4932 from 5400 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 14:
4680 divided by 548 is 8 with a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 121967.764598
If we take 4384 away from 4680, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
548 can be fit into 2960 5 times, resulting in a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 121967.7645985
Subtracting 2740 from 2960 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
548 can be fit into 2200 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 121967.76459854
The remainder is 8 after subtracting 2192 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 121967.76459854, with a leftover of 8e-09.
