We're dividing 51687582 by 942 
We want to figure out the number of times 51687582 can be divided by 942.

Let's proceed to step 1:
942 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 942

Moving on to step 2:
The number 942 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 942

On to step 3:
942 goes into 516 0 times with a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 516, we end up with 516.
Bring next digit (8) of the dividend behind the 516 and repeat the process: 5168 / 942

Moving on to step 4:
942 can be fit into 5168 5 times, resulting in a remainder of 458.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 458 after subtracting 4710 from 5168.
Append the next digit (7) from the dividend to 458 and continue with: 4587 / 942

Going ahead to step 5:
When dividing 4587 by 942, we get 4 with a remainder of 819.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we take 3768 away from 4587, we end up with 819.
Bring next digit (5) of the dividend behind the 819 and repeat the process: 8195 / 942

Advancing to step 6:
8195 divided by 942 is 8 with a remainder of 659.
Put 8 as the next digit of the answer. 
Result so far: 548.0
Deduct 7536 from 8195 and we're left with 659.
Grab the next digit (8) from the dividend, add it to 659, then carry on: 6598 / 942

Moving on to step 7:
942 can be fit into 6598 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 5487.0
If we take 6594 away from 6598, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 942

Advancing to step 8:
When dividing 42 by 942, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 54870.0
If we take 0 away from 42, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
942 goes into 420 0 times with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 54870.0
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
942 goes into 4200 4 times with a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 54870.04
The remainder is 432 after subtracting 3768 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 11:
When dividing 4320 by 942, we get 4 with a remainder of 552.
The next digit of our result is 4. 
Result so far: 54870.044
If we take 3768 away from 4320, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final outcome is 54870.044, with a leftover of 0.0552.
